  • An investigation of ESD protection for magnetoresistive heads

    Many precautions are taken to avoid damaging electrostatic discharge (ESD) through disk drive magnetic recording heads featuring readback via a magnetoresistive (MR) sensor. By optimizing protective spark-gaps (PSG) in the recording head, the extent of ESD damage can be reduced. Human Body Model (HBM), Machine Model (MM) and Charged Device Model (CDM) transients are applied to simulated soft-adjacent-layer (SAL)-biased MR heads with and without protective spark-gaps. Design principles for ESD-damage-suppressing spark-gaps in MR heads are developed and several implementations compared.

  • Magnetoresistors for vehicle detection and identification

    A magnetoresistor sensor is proposed as an alternative to the conventional magnetic loop for automobile detection and traffic control. Underground magnetic loops have been used to detect the presence of vehicles at the roadway intersections for the past few decades. The detection scheme is based on the principle that the magnetic flux linking the buried loop changes whenever a vehicle is present above the plane of the loop. However, it has long been recognized that these magnetic loops are intrusive, expensive to install, and costly to maintain. Besides not very reliable, they are incapable of detecting the differences between cars, trucks, and motorcycles. In addition to the permanent magnetism inherent to a vehicle, the Earth's magnetic field also induces in it a magnetic dipole field. The vector sum of the induced and permanent fields may be exploited by a vehicle recognition and identification system or device. By means of systems modeling and computer simulation, the paper analyzes and evaluates such a vehicle sensing device.

  • The duality that relates magnetic noise to electric shot noise

    Statistical treatment of the succession in time of the Barkhausen-noise pulses shows that magnetic noise possesses characteristics that are similar to those of electric shot noise. On the other hand, the electric shot-noise intensity in a noisy component is known to be related directly to the square root of the dc current through the component. Hence, it is intriguing to relate in the same manner the magnetic-noise flux-fluctuations to a magnetic entity similar to the dc current in the electric case. The present work is a successful attempt to demonstrate that such relationship exists. This is attained by employing the duality that relates the time-derivative of the magnetic flux to the electric current. The magnetic noise measurements of commercially available thin-film magnetoresistors confirm the applicability of the proposed approach. The noise was generated by exciting the magnetoresistors by an ac magnetic field along their easy axes. The level of the resulted flux time- derivative was changed by varying the excitation frequency.

  • Long term stability of magnetoresistive bubble detectors

    Various failure modes of Permalloy magnetoresistors are evaluated. Magnetic failure of magnetoresistors can be eliminated by passivation with evaporated SiO and sputtered Al2O3and Si3N4films. Effect of the permalloy/Au interaction at the sensor/lead metallization interface was investigated by high current and temperature stressing (5.5 × 106A/cm2and 330°C) of actual sensors, and by He-ion nuclear backscattering and x-ray diffraction analysis of Au/permalloy sheet film couples. Stripe cracking failures occur at the negative terminal. Significant interdiffusion of Au/permalloy can occur. However, the interdiffusion is not particularly deleterious to sensor performance.

  • Bridging the gap between AMR, GMR, and Hall magnetic sensors

    By integrating a magnetic flux concentrator (IMC) at the surface of a Hall magnetic sensor, we can dramatically improve its characteristics. Here we compare the performance of a new IMC Hall sensor ASIC with the performance of traditional magnetic field sensors, such as AMR, GMR, and conventional Hall sensor ASICs. We find that the detectivities of AMRs and GMRs for AC magnetic fields are much better than those of Hall ASICs; for low-frequency fields, the performance gap is smaller; but for DC fields, the resolution of the IMC Hall ASIC is much better than that of GMRs and approaches the resolution of a nonswitched AMR. Also according other parameters, the IMC Hall ASIC is positioned in the gap between AMRs, GMRs, and the conventional Hall ASIC magnetic field sensors.

  • Realization of a Magnetoresistive Gyrator Circuit

    The realization of a gyrator network with the use of rnagnetoresistive devices is analyzed from the viewpoint of minimizing the required number of negative- resistance devices. It is demonstrated that the special nature of these devices, which permits their output polarities to be easily reversed, enables the gyrator network to be realized using only one negative-resistance element. The devices investigated herein are the cryotron operating in a linear mode and the conventional magnetoresistive device. The various methods of connecting the devices are compared, and considerations are given to the advantages and the disadvantages involved in the practical implementation of the various circuit arrangements.

  • Soft product assembly and manipulation

    With soft products, especially those with loose filing, the package dynamics are continually changing and the and thus cannot be successfully modelled. The conformance of such products when mechanically handled also results in a high probability of packet rupture. A collaborative project, funded by EPSRC and DTI under the LINK initiative, is investigating the problems of handling soft products in the form of bagged loose materials. The partners De Montfort University, Birmingham University and Robotec Ltd., have designed a prototype system utilising air handling to cushion fragile products and a vision system to determine package orientation. The vision system is utilised as a sensor to provide nonconformance input to a novel control and actuator system. The actuators utilise piezo-mechanically operated air microjets to steer the packages into the correct orientation and propel them along a pneumatic support "cushion". Actuator systems are also being designed utilising magnetostrictive materials and/or moire mesh techniques. The control system is reactive and adaptive and makes use of distributed parallel microcontrollers. The controllers are based on fuzzy rules and have elements of intelligent learning activity to modify the rules.<<ETX>>

  • Vortex magnetization state in a GMR spin-valve type field sensor

    Summary form only given. In this paper, we present a different approach by using circularly shaped elements exhibiting a different magnetization state. The magnetic vortex is one of the fundamental magnetization ground states occurring in disk-shaped thin film elements and is characterized by minimization of the demagnetizing energy at the expense of exchange energy. The state is described as free of hysteresis and planar stray-fields, and discussed as potential oscillator in spin-torque systems, memory bits and magnetic field sensors. In order to compare important parameters like resistance, magnetoresistance amplitude, sensitivity, hysteresis, critical fields like nucleation and annihilation fields in dependence on the free layer thickness and disk radius, single and arrays (10 and 1750 in number) of GMR disks have been fabricated by optical lithography and contacted.
