中文摘要	The magnetic measurements of the single crystal of Mn-3 single-molecule magnet under high pressure at T=2 K have been performed. We find both the antiferromagnetic intermolecular coupling parameter J and the effective energy barrier to vary compared with the measurements at low pressure. The increase of \|J\| is estimated to be 12% at 0.7 GPa when compared with that of 0 GPa, whereas the effective energy barrier becomes smaller with increasing pressure. Our results demonstrate that the intermolecular interaction of single-molecule magnet can be changed by pressure. Compared with the normal magnetic alloy, the effect of pressure on the magnetic properties of Mn-3 is much more prominent, which implies that Mn-3 may have great potential in magnetic multifunctional material.
