| Abstract | The phase diagram of κ-(BEDT-TTF)2Cu[N(CN)2]Br around the metal-insulator (MI) boundary controlled by partially deuteration and by cooling rate through the 80 K anomaly has been investigated by resistivity measurements under magnetic fields. According to approach to the critical region of MI transition from the metallic side by the increase of cooling rate, a) in addition to the deuteration and the cooling rate dependence of the resistance maximum, the hump of resistance, observed at 33.5 K in the partially deuterated sample for slowly cooled, is shifted towards a lower temperature, b) the temperature of the resistance hump at 9.5 K with the hysteresis of resistance increases. Our results suggest that these anomalies are related to the phase separation of the metallic and insulator phase around the MI boundary. |
