Spinmotive Force due to Intrinsic Energy of Ferromagnetic Nanowires
Yuta Yamane, Jun'ichi Ieda, Jun-ichiro Ohe +2
We study, both analytically and numerically, a spinmotive force arising from inherent magnetic energy of a domain wall in a wedged ferromagnetic nanowire. In a spatially-nonuniform…
Equation-of-motion approach of spin-motive force
Yuta Yamane, Jun'ichi Ieda, Jun-ichiro Ohe +2
We formulate a quantitative theory of an electromotive force of spin origin, i.e., spin-motive force, by the equation-of-motion approach. In a ferromagnetic metal, electrons couple…
Spin-dependent inertial force and spin current in accelerating systems
Mamoru Matsuo, Jun'ichi Ieda, Eiji Saitoh +1
The spin-dependent inertial force in an accelerating system under the presence of electromagnetic fields is derived from the generally covariant Dirac equation. Spin currents are e…
Spin current generation due to mechanical rotation in the presence of impurity scattering
Mamoru Matsuo, Jun'ichi Ieda, Eiji Saitoh +1
We theoretically investigate the generation of spin current from a uniformly rotating body with impurity scattering on the basis of the spin dependent transport equation. The spin…
Acoustic spin pumping as the origin of the long-range spin Seebeck effect
Ken-ichi Uchida, Hiroto Adachi, Toshu An +5
The spin Seebeck effect (SSE) is known as the generation of 'spin voltage' in a magnet as a result of a temperature gradient. Spin voltage stands for the potential for spins, which…
Giant enhancement of spin accumulation and long-distance spin precession in metallic lateral spin valves
Y. Fukuma, L. Wang, H. Idzuchi +3
The nonlocal spin injection in lateral spin valves is highly expected to be an effective method to generate a pure spin current for potential spintronic application. However, the s…
