Abstract

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 H _c2. 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.
