Abstract

Current voltage (itI-V) curves CVD-YBa₂Cu₃O_7-δ films near the glass transition temperature T_g in the mixed state are studied as a function of the angle θ between magnetic field andc axis. In the vortex-glass scaling analysis of I-V curves, it is found that the glass critical exponentsare independent of θ, and do not show a remarkable change even at θ=90°(H⊥c). Our results indicates that periodic plane-like intrinsic pinning is not so effective near T_g and vortices are pinned at the random point-like disorder for all field directions.
