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 χ⊥ (T)is linear function at T≪J and quadratic one at T∽J. A comparison with calculations for a nonlinear σ model without skyrmions and spin-wave results for T=0 is given.
