摘要
Magnetoresistance for field close to the parallel to the superconducting planes direction has been studied in organic superconductor kappa-(BEDT-TTF)(2)Cu[N(CN)(2)]Br. The results show a first order phase transition between the superconducting state and the normal state at the upper critical field H-c2. The Is' order transition is evidenced by the hysteretic behavior in the magnetoresistance as a function of field or angle between the field and the plane. A possible model is discussed.
