Thermally Driven Ratchet Motion of Skyrmion Microcrystal and Topological Magnon Hall Effect
M. Mochizuki, X. Z. Yu, S. Seki +6
Spontaneously emergent chirality is an issue of fundamental importance across the natural sciences. It has been argued that a unidirectional (chiral) rotation of a mechanical ratch…
Spin model of magnetostrictions in multiferroic Mn perovskites
Masahito Mochizuki, Nobuo Furukawa, Naoto Nagaosa
We theoretically study origins of the ferroelectricity in the multiferroic phases of the rare-earth (R) Mn perovskites, RMnO3, by constructing a realistic spin model including the…
Theory of electromagnon in the multiferroic Mn perovskites: Vital role of higher harmonic components of the spiral spin order
Masahito Mochizuki, Nobuo Furukawa, Naoto Nagaosa
We study theoretically the electromagnon and its optical spectrum (OS) of the terahertz-frequency regime in the magnetic-spiral-induced multiferroic phases of the rare-earth (R) Mn…
