摘要
We explored the vortex phase diagram of YBCO using electrical transport and AC specific heat measurements. The evolution of the phase diagram with increasing defect density and varying defect geometry is discussed, with particular emphasis on the lower critical point H-lep of the first-order vortex melting line.
