Abstract
A coupled Ising chain model of the spin interactions in certain rare-earth chlorides and hydroxides is developed. The specific heat and susceptibility are derived analytically as functions of temperature in the two-chain case by the transfer-matrix method. These results are then compared with the available experimental data on the rare-earth chlorides and interaction parameters are derived for PrCl3 and NdCl3.Keywords
