Abstract

The magnetization and critical magnetization current densities of sinter-forged YBa₂Cu₃O_7-δ samples of nearly theoretical density have been studied. The magnetization curves can be well fitted by Kim's critical state equation J_c(B)=α/(B ₀+B) with a flat plate geometry. The results revealed an anisotropy in the lower critical field and the critical current density with respect to the forging axis. The deduced critical current density in the favorable direction is larger than the value of isotropic polycrystalline samples.
