Observation of the Pressure Dependent Reversible Enhancement of T_c and Loss of the Anomalous Constricted Hysteresis for [Ru₂(O₂CMe)₄]₃[Cr(CN)₆]

The temperature and pressure dependencies of the magnetization, M(T,P), of cubic [Ru2(O2CMe)4]3[Cr(CN)6] reveals that Tc reversibly increases with increasing pressure up to 83 % to 59 K at 12.8 kbar (2.1 K kbar–1), and the pressure dependence of the hysteresis, M(H,P), shows that the anomalous constricted hysteresis observed at ambient pressure disappears at higher pressure (see figure).
