Abstract

In the contribution we present the effect of pressure on magnetic properties of molecule based magnet KMnCr(CN)₆. Applied pressure affects magnetization curves only marginally. The saturation is reached at higher magnetic fields under pressure, but the effect of the pressure on the values of saturated magnetization µ_s, remnant magnetization µ_r and coercive field H_C are almost negligible. Observed pronounced increase of the Curie temperature T_C with increasing pressure can be attributed to strengthening of antiferromagnetic superexchange interaction. Additionally we observed double magnetic transition induced by hydrostatic pressure. All pressure changes were fully reversible.
