A class of materials simulating the two‐dimensional Heisenberg antiferromagnets with an XXZ spin anisotropy is studied using the method of double‐time‐temperature Green’s functions (GF) with spin S = 5/2 within Tyablikov’s decoupling approx

It is shown that an analytical solution for the solitons in an anisotropic Heisenberg model does not satisfy the essential demands for being a soliton solution.

The low-temperature expansion of the relative magnetization of two anisotropic Heisenberg models is discussed. It is shown that due to the existence of the temperature independent energy gap, the dimensionless temperature cannot be applied as the sma
