Automatic technique for measuring the Polder resonance in ferrite spheres

M. Rojo; J. Margineda; J. Munoz IEEE Transactions on Instrumentation and Measurement, 1991

An automatic technique for measuring the parameters of Polder resonance in polycrystalline ferrite spheres is proposed. The diagonal elements of the external susceptibility tensor versus DC magnetic field are calculated from the changes in resonance frequency and unloaded Q factor of a microwave cavity by perturbation theory. From these diagonal elements, all the elements of the intrinsic permeability tensor can ...


Nonreciprocal magneto-optics for millimeter waves

G. F. Dionne; J. A. Weiss; G. A. Allen IEEE Transactions on Magnetics, 1988

The magnetooptical principles that form the basis for isolators and circulators at infrared wavelengths, i.e. 0.8 and 1.3 μm, have been successfully applied at 1 cm (35 GHz). Unlike the infrared case, which functions on the wings of a crystal-field absorption line, millimeter-wave rotation originates from ferrimagnetic resonance, and its magnitude is directly proportional to the ferrite magnetization. The basic ...


Optimum design for WYE-junction circulator

Jiang Renpei; Wei Chongyue IEEE Transactions on Magnetics, 1988

Formulas for the eigenimpedance of YY-junction circulators are proposed. The eigenimpedance is used to find a circulator equation that satisfies the circulating conditions and a design procedure that differs from those based on admittance slope. Examples are given for calculating circulator characteristics by CAD or optimization methods, taking ferrite electromagnetic losses into account


Friction and adhesion forces on magnetic disk surfaces

R. Kaneko; T. Miyamoto IEEE Transactions on Magnetics, 1988

Distributions of friction and adhesion forces between magnetic disk surfaces and tips have been measured with high accuracy. When the frictional force between a very sharp tip and a nonlubricated disk is measured, stick-slip motions are observed. Lubrication prevents these motions and lowers frictional coefficients. When adhesion force is measured, several sharp peaks are observed for nonlubricated surfaces. Lubrication lowers ...


Nanomagnetism and domain structure of sintered nickel-zinc ferrites studied by magnetic force microscopy

A. Dias Nanotechnology, 2004. 4th IEEE Conference on, 2004

The nanomagnetic structure of hydrothermal NiZn ferrites sintered at various temperatures was studied in this work through magnetic force microscopy using different magnetically characterized tips. The magnetic patterns according to the tip employed were correlated to the magnetic induced field generated by these different coated tips. Nickel ferrites were produced at 200°C by hydrothermal synthesis and sintered at temperatures ranging ...
