Abstract

The vortex order-disorder phase transition line in (La0.937Sr0.063)2CuO4 exhibits a steep concave decrease throughout the whole temperature range. This unusual behavior is explained postulating that in (La0.937Sr0.063)2CuO4, both thermal and disorder-induced fluctuations take part in destabilizing the vortex lattice. Irradiation of the samples with electrons causes a significant decrease in both the magnitude of the transition field and the curvature of the transition line. These results are interpreted as caused by the enhanced role of disorder-induced fluctuations as compared with thermal fluctuations.
