Substitution effects in RuO single crystals
Shubhankar Paul, Kunihiko Yamauchi, Shogo Yamashita +7
RuO has emerged as one of the leading candidates for investigating altermagnetism. Recent quantum oscillation and angle-resolved photoemission spectroscopy measurements found t…
First-principles study of magnetic and spin-dependent transport properties of Mn2VZ (Z = Al, Ga) with negative spin polarization using a disordered local moment approach at finite temperatures
Shogo Yamashita, Esita Pandey, Gerhard H. Fecher +2
First-principles studies were performed on two Mn-based ferrimagnetic Heusler compounds with L21 and B2 structures, that is, Mn2VZ (Z = Al or Ga). The aim was to investigate their…
First-principles study of exchange stiffness constant of half-metallic Heusler alloys Co2MnZ (Z= Si, Al) at finite temperatures: Spin fluctuation-induced effective half metallicity
Shogo Yamashita, Akimasa Sakuma, Mikihiko Oogane
We performed first-principles calculations at finite temperatures to investigate the temperature dependence of the magnetic properties, such as exchange stiffness constants and Cur…
Light-induced torque in ferromagnetic metals via orbital angular momentum generated by photon-helicity
Koki Nukui, Satoshi Iihama, Kazuaki Ishibashi +7
We investigated photon-helicity-induced magnetization precession in CoPt alloy thin films. In addition to field-like torque, attributable to magnetic field generation…
Magnetization and exchange-stiffness constants of Fe-Al-Si alloys at finite-temperatures: A first-principles study
Shogo Yamashita, Akimasa Sakuma
We investigated the magnetic properties of Sendust (Fe-Al-Si) alloys not only at 0 K but also at finite-temperatures by means of the first-principles calculations assuming A2, B2,…
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…
