This talk reports high pressure magnetometry of phase pure polycrystalline MgCr2O4 conducted using an HMD pressure cell attachment for the MPMS3 SQUID-based magnetometer. The results indicate significant changes in the low-temperature response of the material’s magnetic susceptibility under applied pressures of up to approximately 1.5 GPa. Neutron spectroscopy measurements will be presented along with Landau-Lifshitz calculations to further elucidate the influence of pressure on the magnetic interactions giving rise to the complex phase diagram.
