In this work, a cheap and simple composite ME technique has been introduced to comprehensively study the vortex phases in type-II High Tc superconductor YBa2Cu3O7-x polycrystalline. We demonstrate that this method can comprehensively investigate and plot the vortex phase diagram, including the Hc1, irreversible line, Hc2 and distinguishing among vortex glass, vortex liquid, non-vortex states. Moreover, it can probe the dynamic response of vortex liquid phase under different frequency and stimulus strength. Most important, it can quantitatively measure the density of vortex in the vortex solid phase.
