A microscopic design rule for spin supersolids in triangular-lattice magnets
Ryota Ono, Jun'ichi Ieda, Michiyasu Mori +1
Spin supersolids emerge as a central topic in frustrated magnetism, motivating the search for realization in quantum materials. To this end, we study the origin of exchange anisotr…
Josephson diode effect via a non-equilibrium Rashba system
Michiyasu Mori, Wataru Koshibae, Sadamichi Maekawa
A non-equilibrium state in a Rashba system under an in-plane magnetic field is identified as the origin of the Josephson diode effect. This state is induced by a current bias--nece…
Theory of the spin Seebeck effect influenced by crystal-field excitations in TbFeO
Michiyasu Mori, Bruno Tomasello, Timothy Ziman
The spin Seebeck effect (SSE) is a phenomenon of thermoelectric generation that occurs within a device consisting of a bilayer of a metal and a ferromagnet. When TbFeO$_{12…
Magnetic Structures and Spin-wave Excitations in Rare-Earth Iron Garnets near the Compensation Temperature
Michiyasu Mori, Timothy Ziman
We introduce a simple model for the ferrimagnetic non-collinear ``magnetic umbrella" states of rare-earth iron garnets (REIG), common when the rare-earth moments have non-zero orbi…
Shapiro steps in charge-density-wave states driven by ultrasound
Michiyasu Mori, Sadamichi Maekawa
We show that ultrasound can induce the Shapiro steps (SS) in the charge-density-wave (CDW) state. When ultrasound with frequency and a dc voltage are applied, the SS occur at t…
Half-integer Shapiro Steps in Strong Ferromagnetic Josephson Junctions
Yunyan Yao, Ranran Cai, See-Hun Yang +7
We report the experimental observation of half-integer Shapiro steps in the strong ferromagnetic Josephson junction (Nb-NiFe-Nb) by investigating the current-phase relation under r…
