“…We have calculated the magnetization of GdCl, to order (l/z)' using equation 24, and the results are shown in figure 6 for the 'low field' case discussed previously where the factor ( H -yyR,N,) is zero. Curve A shows the calculated magnetization, and curve B represents experimental measurements by Scheller (1971). The (l/z)O molecular field results are shown by the broken curve and Figure 6.…”

The magnon spectrum and thermodynamic properties of GdCI,, a ferromagnet in which the dipolar interactions are comparable in magnitude with the exchange interactions. are investigated both analytically and numerically. The calculations make use of formal results derived previously by Cottam for a general ferromagnetic insulator with dipole-dipole interactions. The magnon energies at low temperatures are calculated, including the leading order effects of spin wave interactions. The dispersion relation is found to be very anisotropic, and in particular it has a minimum energy gap of approximately 0,36 K at k = (0, 0,0,28)A By numerical integration over the whole Brillouin zone, results are obtained for the spontaneous magnetization over a wide range of temperatures, and the Curie temperature is estimated. A comparison is made with experimental data. Calculations are also carried out for the static susceptibility and the magnetic specific heat.

“…The relative magnetization M ( T ) / M , for GdC1, as a function of temperature for zero applied field. Curve A is the calculated magnetization to order (llz)', and curve B represents experimental measurements by Scheller (1971). The broken curve shows the magnetization in the molecular field approximation (order (11~)').…”
