Abstract
Specific heat measurements below 1 K on [Cr(NH3)6] [Cr(CN)6] and [Cr(NH3)5 (H2O)] [Co(CN)6] are reported. The first compound orders as a Heisenberg bcc S = 3/2 ferromagnet. The second remains paramagnetic showing only a crystal field Schottky behaviour. Previous results on [Cr(NH3)5 (H2O)] [Cr(CN)6], where the water molecule is randomly localized, are interpreted within a bond-dilution scheme.
