dc.description.abstractThe vortex melting transition Tm in several untwinned and twinned crystals is measured resistively in fields up to 8T. A Lindemann criterion for vortex lattice melting is obtained in addition to a sharp hysteresis in the magnetoresistance at Bm supporting a first-order phase transition. The anisotropy of twin boundary pinning and its reduction of the 'kink' in ρvariant(T) associated with the first-order melting transition is discussed in samples with very dilute twin boundaries. We also report on the direct suppression of the melting transition by intrinsic pinning for H norm of matrix ab and by electron-irradiation-induced point defects. © 1994.en
