Flux pinning energies and their distribution in the high-Jc YBa2Cu307 superconductor prepared by the melt-textured growth (MTG) method were determined at liquid nitrogen temperature by using rotating sample magnetic measurements. Anisotropy was found in the distribution of the pinning energies in th
Complex AC susceptibility measurements have been performed systematically on a melt-textured growth YBa2Cu206+ sample. The activation energy has been determined to be U(T, H, j)= Uo[1-(T/Tx)2]3/2(Ho/H)n ln(jo/j), with n = 0.46 and n ~ 0.59 for H II ab and H II c, respectively. The expressions U(H) ~
