Abstract

Single-molecule magnet (SMM) clusters of Mn₇ can have ground states of S = 11 or S = 16, depending upon the local symmetry of the clusters. The possibility of inducing a switching of the spin ground state configuration as a function of pressure was investigated by measuring the temperature dependence of the magnetic susceptibility, χ_M(3 K ≤ T ≤ 40 K), using a home-made resonant coil magnetometer operated near 6 MHz and equipped with a pressure cell capable of producing PK2:5 GPa. The results indicate the ground states of both materials are robust in the temperature?pressure?frequency parameter space that was probed.
