Dynamic scaling of ac susceptibility in melt-textured YBCO superconductors

Based on vortex glass phase transition analysis, using homogeneous function analysis, it is very convenient to obtain the dynamic scaling law of ac susceptibility in high temperature superconductors. The experimental results of melt-textured YBCO system and other high temperature superconductors are consistent with the scaling function. The critical exponent γ is estimated from the scaling result. The asymptotic properties at low frequencies are discussed.
