Magnetoelectric effect in band insulator-ferromagnet heterostructures
Ken N. Okada, Yasuyuki Kato, Yukitoshi Motome
We theoretically study magnetoelectric effects in a heterostructure of a generic band insulator and a ferromagnet. In contrast to the kinetic magnetoelectric effect in metals, refe…
Magnetic Structural Unit with Convex Geometry: a Building Block Hosting an Exchange-striction-driven Magnetoelectric Coupling
Kenta Kimura, Yasuyuki Kato, Kunihiko Yamauchi +10
We perform a combined experimental and theoretical study of a magnetic-field () induced evolution of magnetic and ferroelectric properties in an antiferromagnetic material Pb(Ti…
Periodicity-free unfolding method of electronic energy spectra: Application to twisted bilayer graphene
Taichi Kosugi, Hirofumi Nishi, Yasuyuki Kato +1
We propose a novel periodicity-free unfolding method of the electronic energy spectra. Our new method solves a serious problem that calculated electronic band structure strongly de…
