Abstract
The specific heat and zero-field magnetic susceptibilities of [(CH3)3NH] MnX3.2H2O (X=Cl Br) are reported. The isotropic Heisenberg model for linear chains offers a reasonable fit to the data, but a substantial anisotropy is also observed. For the chloride, TN = 0.98 K, J/k = -0.36 K, and zJ′/k = -0.55 K; for the bromide, TN = 1.56 K, J/k = -0.41 K, and zJ′/k = -0.74 K. A canted antiferromagnetic structure is proposed.
