Large Hall angle of vortex motion in high-T_c cuprate superconductors revealed by microwave flux-flow Hall effect

We investigated the nature of the quasi-particle state in the vortex core by means of the flux-flow Hall effect measurements at 15.8 GHz. We measured the flux-flow Hall effect in cuprate superconductors, Bi_{2}Sr_{2}CaCu_{2}O_{y} and YBa_{2}Cu_{3}O_{y} single crystals, whose equilibrium B-T phase diagrams were different. As a result, we found that... Show more
