Plasmon effect on the Coulomb pseudopotential in the McMillan equation
Kazuhiro Sano, Mithuki Seo, Kohji Nakamura
We examine the Coulomb pseudopotential in the McMillan equation applying to the superconductivity of heavily doped semiconductors. Systematic calculation using the first-prin…
Symmetry of Berry and spin Berry curvatures in ferromagnetic CoPt
Guanxiong Qu, Kohji Nakamura, Masamitsu Hayashi
The intrinsic spin Hall conductivity and the anomalous Hall conductivity of ferromagnetic L1-CoPt are studied using first principle calculations of the spin Berry and Berry cur…
Magnetization direction dependent spin Hall effect in 3d ferromagnets
Guanxiong Qu, Kohji Nakamura, Masamitsu Hayashi
We have studied the intrinsic spin Hall conductivity of 3d transition metal ferromagnets using first-principles calculations. We find the spin Hall conductivity of bcc Fe and fcc N…
Tunable inverse spin Hall effect in nanometer-thick platinum films by ionic gating
Sergey Dushenko, Masaya Hokazono, Kohji Nakamura +3
Electric gating can strongly modulate a wide variety of physical properties in semiconductors and insulators, such as significant changes of conductivity in silicon, appearance of…
Enhanced perpendicular magnetocrystalline anisotropy energy in an artificial magnetic material with bulk spin-momentum coupling
Abdul-Muizz Pradipto, Kay Yakushiji, Woo Seung Ham +8
We systematically investigate the perpendicular magnetocrystalline anisotropy (MCA) in CoPt/Pd-based multilayers. Our magnetic measurement data shows that the asymmetric Co/Pd/P…
