Abstract
We use the Green's function formalism for the spin-wave operators to study the low-temperature behavior of the canted-paramagnetic phase boundary of anisotropic antiferromagnets. The analytic asymptotic expressions for this boundary are compared with the results of a self-consistent numerical calculation which should be valid for a larger temperature interval. Also, we apply these results to account for the experimental data pertaining to the uniaxial antiferromagnets NiCl2·6H2O and NiCl2·4H2O, and to the transversally anisotropic exchange antiferromagnet CoCl2·6H2O. We verify that the uniaxial systems behave according to a T32-law, while the transversal system is shown to exhibit a T2 asymptotic dependence on temperature.
