        Real-time Analysis of the Spinmotive Force due to Domain Wall Motion

        Jun’ichi Ieda,Sadamichi Maekawa,Yuta Yamane 한국물리학회 2013 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.62 No.12

        Using numerical simulations, we study the spinmotive force induced by domain wall motion in ahigh magnetic field region far above the Walker breakdown field. We find that the DC componentof the spinmotive force scales with the applied magnetic field even in a field range where the wallmotion is no longer associated with periodic angular rotation of the wall magnetization. As the fieldis increased, spikes in the voltage signals start to appear, which are mainly attributed to vortex corecollisions, nucleation, and annihilation, and this tendency is enhanced with further increases in thefield. At high fields, the slope of the generated DC voltage vs. applied field curve is expected todepend only on the spin polarization of conduction electrons and, thus, can be used to accuratelydetermine the degree of spin polarization in various materials.

        Effects of Mechanical Rotation and Vibration on Spin Currents

        Mamoru Matsuo,Jun’ichi Ieda,Sadamichi Maekawa,Eiji Saitoh 한국물리학회 2013 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.62 No.10

        We discuss theoretically the generation of spin currents in both rotationally and linearly accelerated systems. The spin-orbit interaction modified by inertial effects is derived from the low energy limit of the generally covariant Dirac equation. It is shown that the spin-orbit interaction is responsible for the generation of spin currents by mechanical rotation and vibration. We also study effects of impurity scattering on the mechanically induced spin current, and calculate the spin accumulation by solving the spin diffusion equation with the spin-source term originating from the inertial effects.
