Colossal enhancement of spin-chirality-related Hall effect by thermal fluctuation
Yasuyuki Kato, Hiroaki Ishizuka
The effect of thermal fluctuation on the spin-chirality-induced anomalous Hall effect in itinerant magnets is theoretically studied. Considering a triangular-lattice model as an ex…
Magnetoelectric behavior from cluster multipoles in square cupolas: Study of Sr(TiO)Cu(PO) in comparison with Ba and Pb isostructurals
Yasuyuki Kato, Kenta Kimura, Atsushi Miyake +8
We report our combined experimental and theoretical study of magnetoelectric properties of an antiferromagnet Sr(TiO)Cu(PO), in comparison with the isostructurals Ba(Ti…
Multiple- magnetic orders in Rashba-Dresselhaus metals
Ken N. Okada, Yasuyuki Kato, Yukitoshi Motome
We study magnetic textures realized in noncentrosymmetric Kondo lattice models, in which localized magnetic moments weakly interact with itinerant electrons subject to Rashba and D…
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…
Antiferromagnetic Kitaev Interaction in -Electron Based Honeycomb Magnets
Seong-Hoon Jang, Ryoya Sano, Yasuyuki Kato +1
We theoretically propose a family of -electron based magnets that realizes Kitaev-type bond-dependent anisotropic interactions. Based on {\it ab initio} calculations, we show th…
Global constraints on fluxes in two different anisotropic limits of a hypernonagon Kitaev model
Yasuyuki Kato, Yoshitomo Kamiya, Joji Nasu +1
The Kitaev model is an exactly-soluble quantum spin model, whose ground state provides a canonical example of a quantum spin liquid. Spin excitations from the ground state are frac…
