原始语种摘要: We study the electric transport properties of Li x (NH3) y Fe2(Te z Se )2 single crystals with and 0.6 in the mixed state. Thermally-activated flux-flow, vortex glass and flux-flow Hall effect (FFHE) behaviors are observed. Experimental results show that there are rich vortex phases existing in these systems and the vortex liquid states occupy broad regions of phase diagrams. Further analysis suggests that thermal fluctuation plays an important role in the vortex phase diagrams of Li x (NH3) y Fe2(Te z Se )2. Moreover, for Li x (NH3) y Fe2Se2, there is no sign reversal of FFHE in the mixed state and a...
