Effects of point defects on the phase diagram of vortex states in high-Tc superconductors in B//c axis

Yoshihiko Nonomura, Xiao Hu

The phase diagram for the vortex states of high- superconductors with point defects in axis is drawn by large-scale Monte Carlo simulations. The vo…

Bicritical and tetracritical phenomena and scaling properties of the SO(5) theory

Xiao Hu

By large scale Monte Carlo simulations it is shown that the stable fixed point of the SO(5) theory is either bicritical or tetracritical depending on the effective interaction betw…

Zigzag Charge Ordering in alpha'-NaV2O5

Tetsuo Ohama, Atsushi Goto, Tadashi Shimizu +4

23Na NMR spectrum measurements in alpha'-NaV2O5 with a single- crystalline sample are reported. In the charge-ordered phase, the number of inequivalent Na sites observed is more th…
