Abstract

The dc-magnetization on high-quality single crystals of the title organic superconductors reveal indications for strong thermal fluctuations in fields perpendicular to the planes, i.e. a field-induced rounding of the transition and a field-independent magnetization at M*(T*,H) for H ≤ 10kOe. The mixed-state properties are governed by an extended range in the H-T plane where the magnetization is entirely reversible. The lower boundary of this range - the so-called irreversibility line - follows an exponential T dependence.
