First-principles prediction of phase transition of YCo from self-consistent phonon calculations
Guangzong Xing, Yoshio Miura, Terumasa Tadano
Recent theoretical study has shown that the hexagonal YCo is dynamically unstable and distorts into a stable orthorhombic structure. In this study, we show theoretically that t…
Band-folding-driven high tunnel magnetoresistance ratios in (111)-oriented junctions with SrTiO barriers
Keisuke Masuda, Hiroyoshi Itoh, Yoshiaki Sonobe +3
We theoretically study the tunnel magnetoresistance (TMR) effect in (111)-oriented magnetic tunnel junctions (MTJs) with SrTiO barriers, Co/SrTiO/Co(111) and Ni/SrTiO$_…
Understanding magnetocrystalline anisotropy based on orbital and quadrupole moments
Yoshio Miura, Jun Okabayashi
Understanding magnetocrystalline anisotropy (MCA) is fundamentally important for developing novel magnetic materials. Therefore, clarifying the relationship between MCA and local p…
Lattice dynamics and its effects on magnetocrystalline anisotropy energy of pristine and hole-doped YCo from first principles
Guangzong Xing, Yoshio Miura, Terumasa Tadano
We study the lattice dynamics effects on the phase stability and magnetocrystalline anisotropy (MCA) energy of CaCu-type YCo at finite temperatures using first-principles c…
Spin-scattering asymmetry at half-metallic ferromagnet/ferromagnet interface
Y. Fujita, Y. Miura, T. Sasaki +3
We study spin-scattering asymmetry at the interface of two ferromagnets (FMs) based on a half-metallic CoFeMnSi (CFMS)/CoFe interface. First-principles ballis…
Crucial role of interfacial - exchange interaction in the temperature dependence of tunnel magnetoresistance
Keisuke Masuda, Terumasa Tadano, Yoshio Miura
The tunnel magnetoresistance (TMR) is one of the most important spintronic phenomena but its reduction at finite temperature is a severe drawback for applications. Here, we reveal…
