Spin-glass transition in bond-disordered Heisenberg antiferromagnets coupled with local lattice distortions on a pyrochlore lattice
Hiroshi Shinaoka, Yusuke Tomita, Yukitoshi Motome
Motivated by puzzling characteristics of spin-glass transitions widely observed in pyrochlore-based frustrated materials, we investigate effects of coupling to local lattice distor…
Electronic phase separation in the pyrochlore double-exchange model
Yukitoshi Motome, Nobuo Furukawa
Electronic phase separation and related inhomogeneity is ubiquitously seen in strongly-correlated systems. A typical example is found between ferromagnetic metal and antiferromagne…
Partial Kondo screening in frustrated Kondo lattice systems
Yukitoshi Motome, Kyoya Nakamikawa, Youhei Yamaji +1
We investigate the effect of geometrical frustration on the competition between the Kondo coupling and the Ruderman-Kittel-Kasuya-Yosida interaction in Kondo lattice systems. By va…
Spin chirality ordering and anomalous Hall effect in the ferromagnetic Kondo lattice model on the triangular lattice
Yutaka Akagi, Yukitoshi Motome
We investigate the ground-state phase diagram for the ferromagnetic Kondo lattice model on a triangular lattice by a variational calculation for various spin orderings up to a four…
Quantum melting of charge ice and non-Fermi-liquid behavior: An exact solution for the extended Falicov-Kimball model in the ice-rule limit
Masafumi Udagawa, Hiroaki Ishizuka, Yukitoshi Motome
An exact solution is obtained for a model of itinerant electrons coupled to ice-rule variables on the tetrahedron Husimi cactus, an analogue of the Bethe lattice of corner-sharing…
Nonequilibrium relaxation study of the anisotropic antiferromagnetic Heisenberg model on the triangular lattice
Takahiro Misawa, Yukitoshi Motome
Effect of exchange anisotropy on the relaxation time of spin and vector chirality is studied for the antiferromagnetic classical Heisenberg model on the triangular lattice by using…
