Effect of Pressure on the Magnetic Anisotropy in the Single-Molecule Magnet Mn12-Acetate: An Inelastic Neutron Scattering Study

Effect of Pressure on the Magnetic Anisotropy in the Single-Molecule Magnet Mn12-Acetate: An Inelastic Neutron Scattering Study

The pressure‐dependence of the zero‐field splitting of the S=10 ground state of the single‐molecule magnet Mn12‐acetate was studied by inelastic neutron scattering (INS) at hydrostatic pressures up to 12 kbar (see picture). The anisotropy increases with increasing pressure, and a pressure‐dependent...

Zusammenfassung:The pressure‐dependence of the zero‐field splitting of the S=10 ground state of the single‐molecule magnet Mn12‐acetate was studied by inelastic neutron scattering (INS) at hydrostatic pressures up to 12 kbar (see picture). The anisotropy increases with increasing pressure, and a pressure‐dependent minority species of Mn12‐acetate was observed. The increased anisotropy arises from increases in the single‐ion anisotropy of the Mn3+ building blocks.
