用直流交流磁化率和~（13）1CNMR研究了有机体系K-（BEDT-TTF）2Cu [N（CN）2] Br的氘代盐的电子态.我们发现该系统处于超导相（T_C = 11.5K）和反铁磁相（T_N = 14-15 K）之间的临界区。还发现，通过80 K的快速冷却驱动超导相进入磁相，这是讨论在莫特转变附近的无序的作用。
The electronic state of the deuterated salt of the organic system κ-(BEDT-TTF) 2 Cu [N (CN) 2] Br, has been investigated by dc/ac susceptibility and/13 1 C NMR measurements. We found that the system is situated in the critical region of the transition between a superconducting phase with a T C of∼ 11.5 K and an antiferromagnetic phase with a T N of 14–15 K. It was also found that the rapid cooling through 80 K drives the superconducting phase into the magnetic phase, that is discussed in the light of the role of disorder near the Mott transition.
