Finite-temperature second-order perturbation analysis of magnetocrystalline anisotropy energy of L10-type ordered alloys
Shogo Yamashita, Akimasa Sakuma
We present a novel finite-temperature second-order perturbation method incorporating spin-orbit coupling to investigate the temperature-dependent site-resolved contributions to the…
Perpendicularly Polarized Spin Hall Effects Induced by Spin-Dependent Scattering in Ferromagnetic Metals
Yuta Yahagi, Daisuke Miura, Akimasa Sakuma
Spin currents in ferromagnets afford diverse functionalities. We evaluate the extrinsic spin Hall effects of magnetic impurity scattering in ferromagnetic metals. We show that spin…
Theoretical Study of Extrinsic Spin-current Generation in Ferromagnets Induced by Anisotropic Spin-flip Scattering
Yuta Yahagi, Jakub Zelezny, Daisuke Miura +1
The spin Hall effect (SHE) and the magnetic spin Hall effect (MSHE) are responsible for electrical spin current generation, which is a key concept of modern spintronics. We theoret…
Detecting quadrupole: a hidden source of magnetic anisotropy for Manganese alloys
Jun Okabayashi, Yoshio Miura, Yohei Kota +3
Mn-based alloys exhibit unique properties in the spintronics materials possessing perpendicular magnetic anisotropy (PMA) beyond the Fe and Co-based alloys. It is desired to figure…
Analytic Expression for Magnetic Activation Energy
Daisuke Miura, Akimasa Sakuma
We theoretically investigate the magnetic activation energy of permanent magnets. Practically, it is widely used in a phenomenological form as $\mathcal{F}_\mathrm{B}(H_\mathrm{ext…
Noncollinearity effects on magnetocrystalline anisotropy for FeB magnets
Daisuke Miura, Akimasa Sakuma
We present a theoretical investigation of the magnetocrystalline anisotropy (MA) in FeB ( is a rare-earth element) magnets in consideration of the non-collinearity e…
