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(2)O . 1.7(CH3OH) with T -N = 29 K, were studied. The transition temperature gradually increase s with an increase in pressure and becomes similar to 40 K at 1 GPa. T he pressure dependence of T-N can be semi-quantitatively interpreted i n terms of the shrinkage of the Mn-CN-Mn superexchange pathway. (C) 19 98 Elsevier Science B.V. All rights reserved.
