Generalization of the Affleck-Kennedy-Lieb-Tasaki Model for Quantum Ferromagnetism
Isao Maruyama, Shin Miyahara
We study a spin- ferromagnetic model with exactly-written ground states, known as the partially-magnetized valence bond solid (VBS) states with magnetization , which…
Ferromagnetic Haldane state and dimer multiplet state of quantum ferromagnets
Shin Miyahara, Isao Maruyama
We present a theory of the realization of a ferromagnetic Haldane state in a spin-2 bilinear-biquadratic spin system on an orthogonal-dimer chain. The coexistence of a ferromagneti…
Field Induced Staggered Magnetization and Magnetic Ordering in
M. Clemancey, H. Mayaffre, C. Berthier +6
We present a D NMR investigation of the gapped spin-1/2 compound . Our measurements reveal the presence of a magnetic field induced transverse sta…
Frustration-induced Dodecamer Ordering in the Double-Exchange Spin Ice Model on the Kagomé Lattice
Yoshihiro Shimomura, Shin Miyahara, Nobuo Furukawa
We investigate a detail of a dodecamer cluster ordering in a double-exchange spin ice model on a kagomé lattice. In frustrated systems, ordinary spin orderings are suppressed and m…
