摘要：
Magnetoresistance for field close to the parallel to the superconducting planes direction has been studied in organic superconductor κ-(BEDT-TTF)2Cu[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 Hc2. The 1st 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.
