摘要：

Hydrostatic pressure effects on the structural and magnetic properties were investigated for two potassium-cobalt-iron hexacyanides, K0.12Co[Fe(CN)(6)](0.70)(.)4.87H(2)O (high [Fe(CN)(6)] vacancy concentration v) and K0.36Co[Fe(CN)(6)](0.82)(.)4.56H(2)O (low-v). In both the compounds, we observed a pressure-induced volume transition at 300 K from the large volume (LV) phase to the small volume (SV) phase. In the high-v compound, the magnitude of the effective moment mu(eff) gradually decreases with pressure increases. We ascribed it to the gradual spin state transformation of Co3+ from the high-spin state (S = 2) to the low-spin state (S = 0).
