Abstract
The effects of high pressure, up to 1 GPa, on a Mn-based Prussian blue ferrimagnet, Mn 3 II[Mn III(CN) 6] 2·12H 2O·1.7(CH 3OH) with T N=29 K, were studied. The transition temperature gradually increases with an increase in pressure and becomes ∼40 K at 1 GPa. The pressure dependence of T N can be semi-quantitatively interpreted in terms of the shrinkage of the Mn–CN–Mn superexchange pathway.
