The effect of the surface magnetic anisotropy of the neodymium atoms on the coercivity in the neodymium permanent magnet

Masamichi Nishino, Ismail Enes Uysal, Seiji Miyashita

The Nd permanent magnet (NdFeB) is an indispensable material used in modern energy conversion devices. The realization of high coercivity at finite temperatures is a b…

Dynamical phase transition in Floquet optical bistable systems: An approach from finite-size quantum systems

Tatsuhiko Shirai, Synge Todo, Seiji Miyashita

We study a dynamical phase transition in optical bistable systems subject to a time-periodic driving field. The phase transition occurs in the structure of limit cycle as a functio…

Characterization of localized effective spins in gapped quantum spin chains

Hayate Nakano, Seiji Miyashita

We study properties of localized effective spins induced in gapped quantum spin chains by local inhomogeneities of the lattice. As a prototype, we study effective spins induced in…

Dzyaloshinsky-Moriya interaction and the ground state in S=3/2 perfect kagome lattice antiferromagnet (Cr-jarosite) studied by X-band and high-frequency ESR

Susumu Okubo, Ryohei Nakata, Hitoshi Ohta +9

A single crystal S=3/2 perfect kagome lattice antiferromagnet (Cr-jarosite) has been studied by X-band and high-frequency electron spin resonance (ES…
