Robust Half-Metallic Character and Large Oxygen Magnetism in a Perovskite Cuprate
Xiangang Wan, Masanori Kohno, Xiao Hu
The new perovskite cuprate material SrCaReCuO, which behaves ferrimagnetically and shows an unusually high Curie temperature ( 440 K), is found f…
Many-body spin Berry phases emerging from the -flux state: antiferromagnetic/valence-bond-solid competition
Akihiro Tanaka, Xiao HU
We uncover new topology-related features of the -flux saddle-point solution of the =2+1 Heisenberg antiferromagnet. We note that symmetries of the spinons sustain a built-in…
Orbital order and ferrimagnetic properties of the new compound
Xiangang Wan, Masanori Kohno, Xiao Hu
By means of the LSDA+U method and the Green function method, we investigate the electronic and magnetic properties of the new material of SrCaReCuO. Our LSDA+U c…
Crossover behaviors in liquid region of vortex states above a critical point caused by point defects
Yoshihiko Nonomura, Xiao Hu
Vortex states in high- superconductors with point defects are studied by large-scale Monte Carlo simulations of the three-dimensional frustrated XY model. A critical poi…
Kosterlitz-Thouless phase and continuous melting transition in layered superconductors immersed in a parallel magnetic field
Xiao Hu, Masashi Tachiki
B-T phase diagram and phase transitions of interlayer Josephson vortices are investigated. For magnetic fields above a critical value, we find a Kosterlitz-Thouless (KT) type inter…
Evidence of first-order transition between vortex glass and Bragg glass phases in high- superconductors with point pins: Monte Carlo simulations
Yoshihiko Nonomura, Xiao Hu
Phase transition between the vortex glass and the Bragg glass phases in high- superconductors in is studied by Monte Carlo simulations in the p…
