Abstract
The static magnetic susceptibility is calculated for a two-dimensional (2D) quantum Heisenberg antiferromagnet (AF)S = 1/2 with thermally excited skyrmions at temperatures T < J, where J is the nearest-neighbor exchange constant. It is found that X- (T) is linear function at T much less than J and quadratic one at T similar to J. A comparison with calculations for a nonlinear a model without skyrmions and spin-wave results for T = 0 is given.
