摘要
The antiferromagnetic phase of a deuterated salt of kappa-(BEDT-TTF)(2)Cu[N(CN)(2)]Br is studied by magnetic resonance and resistivity measurements. When the sample is cooled rapidly, antiferromagnetic spin resonance (AFMR) signals are found below 6-8 K. With the aid of resistivity measurements under pressure, the magnetic phase diagram in the weak pressure region is obtained. The cooling-rate and temperature dependence of the AFMR signals are explained in terms of a reentrant superconductivity found close to ambient pressure.
