The authors use a previously developed general procedure for calculating the configuration and stability limits of a steadily translating lossless one- dimensional domain wall in the case of orthorhombic anisotropy with a field applied perpendicular to the easy axis at arbitrary angle. The regions where the three previously identified breakdown mechanisms occur in this more general case are mapped. A ...

Topological spin structures that emerge from the Dzyaloshinskii-Moriya interaction (DMI), such as chiral domain walls and skyrmions have become the focus of intense investigations due to exciting physics and possible applications  . We showed for chiral domain walls (DWs) (where a symmetry - breaking interaction, such as the DMI leads to a unique chirality) that multiple DWs can be ...

The authors use a previously developed general procedure for calculating the configuration and stability limits of a steadily translating lossless one- dimensional domain wall in the case of orthorhombic anisotropy with a field applied perpendicular to the easy axis at arbitrary angle. The regions where the three previously identified breakdown mechanisms occur in this more general case are mapped. A scaling procedure obtained from a refined analysis improves the solution accuracy in those cases in which a transition from a stable to an unstable orientation appears in regions far from the wall center.<<ETX>>
Topological spin structures that emerge from the Dzyaloshinskii-Moriya interaction (DMI), such as chiral domain walls and skyrmions have become the focus of intense investigations due to exciting physics and possible applications  . We showed for chiral domain walls (DWs) (where a symmetry - breaking interaction, such as the DMI leads to a unique chirality) that multiple DWs can be efficiently displaced synchronously using special field geometries  . This overcomes the commonly assumed limitation that magnetic fields cannot be used to move adjacent DWs synchronously and paves the way for new device ideas such as smart cards with non-contact writing .
The magnetic aftereffects (MAEs) phenomena in titanium-doped yttrium iron garnets (Ti-YIG) (Y/sub 3/Fe/sub 5-x/Ti/sub x/O/sub 12/) (0 /spl les/ x /spl les/ 0.2) prepared by a standard ceramic method and sintered up to 1420/spl deg/C in air and CO/sub 2/ atmospheres were demonstrated in this study. The results were interpreted with the aid of defect content data from thermogravimetric measurements. It was observed defect parameter increases with increasing x and a reducing atmosphere is much more effective for increasing the amount of defects. It was also suggested through thermogravimetric and magnetic disaccommodation measurements that only oxygen vacancies and ferrous cations were present in Ti-doped YIG.
Spintronics is an emerging platform for logic circuit design. Though many approaches have been proposed, and several have met with some success, a number of challenges remain. Here, we introduce a new style of magnetic logic- mLogic-enabled by a novel four-terminal device. An input current pulse to the device switches the magnetic state by spin transfer torque-driven domain wall motion, which programs the resistance state of a magnetic tunnel junction in an electrically-insulated but magnetically-coupled path. Despite the low switching ratios of the devices, limited by the tunnel magnetoresistance ratio, logic circuits independent of CMOS may be configured using current- based signaling. Micromagnetic analysis of device performance and the concepts of mLogic circuit design are introduced, with SPICE simulation of logic gates demonstrating correct logic operation at supplies below 100 mV.
This paper presents the design and the characteristics of a nonvolatile memory cell using giant magneto-resistance effects. Unlike other magnetic memory cells, the present cell design exploits the full /spl Delta/R of the spin valve material. A dc voltage difference between the two cell states of 30 mV range has been realized on a cell stripe only 6-microns long, making it compatible with the high-speed sensing schemes presently employed in silicon RAMs. The cell switches states in sub-nanoseconds. Its performance/density is close to that of the static RAM cell.
We have considered the ferromagnetic domain wall pinning caused by a planar type defect characterized by a change in the magnitude of the exchange constant and the uniaxial magnetic anisotropy and in the angular deviation of the magnetic anisotropy axis. Our model is appropriate for bulk material when the magnitude of the radius of curvature of the defect is not large compared to the width of the domain wall. Expressions are obtained and graphed for the coercive force due to such pinning. It is shown that the angular mismatch between the defect and the host material breaks the degeneracy between clockwise and counterclockwise rotating Bloch walls. Further, the results are applied to the Japanese commercial TDK material, Sm2Co10Cu1.48Fe3.16Zr0.194, which shows a fine cellular structure of approximately 500 A scale.
