The temperature and pressure dependencies of the magnetization, M(T,P), of cubic [Ru-2(O2CMe)(4)](3)[Cr(CN)(6)] reveals that T, reversibly increases with increasing pressure up to 83 % to 59 K at 1.2.8 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).
