Magnetoelastic anisotropy in Heusler-type MnCoGa films
Takahide Kubota, Daichi Takano, Yohei Kota +10
Perpendicular magnetization is essential for high-density memory application using magnetic materials. High-spin polarization of conduction electrons is also required for realizing…
Elemental topological Dirac semimetal α-Sn with high quantum mobility
Le Duc Anh, Kengo Takase, Takahiro Chiba +3
α-Sn with a diamond-type crystal structure provides an ideal avenue to investigate novel topological properties owing to its rich diagram of topological phases and simple elemental…
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…
First-principles evaluation of intrinsic, side-jump, and skew-scattering parts of anomalous Hall conductivities in disordered alloys
K. Hyodo, Y. Kota, A. Sakuma
We develop a first-principles procedure for the individual evaluation of the intrinsic, side-jump, and skew-scattering contributions to the anomalous Hall conductivity . Th…
Mechanism of uniaxial magnetocrystalline anisotropy in transition metal alloys
Yohei Kota, Akimasa Sakuma
Magnetocrystalline anisotropy in transition metal alloys (FePt, CoPt, FePd, MnAl, MnGa, and FeCo) was studied using first-principles calculations to elucidate its specific mechanis…
First Principles Calculation of Magnetocrystalline Anisotropy Energy of MnBi and MnB_{1-x}Sn_x
Akimasa Sakuma, Yuki Manabe, Yohei Kota
We calculated the magnetic anisotropy constant Ku of MnBi using a first principles approach, and obtained a negative Ku in agreeable with experimental results. Furthermore, we also…
