The Effect of Intercluster Interactions on the Thermal and Magnetic Properties of (Cr3O(CH3COO)6(H2O)3)Cl-6H2O.

Abstract

Inclusion in the hamiltonian of a perturbing term which describes the pairwise spin exchange between (Cr3O(CH3COO)6(H2O)3)+ equilateral triangular clusters in (Cr3O(CH3COO)6(H2O)3)Cl-6H2O splits the unperturbed ground state into two nondegenerate Kramers doublets. The effect of this splitting is to introduce a Schottky type anomaly in the theoretical heat capacity curve. Excellent agreement between experimental and theoretical heat capacities is found when two crystallographically inequivalent pairs of equilateral trimer sites with different intercluster exchange parameters are assumed. Low-temperature magnetic susceptibility data for this complex are well reproduced by using the parameters which are obtained from the heat capacity data. (Author)
