Summary: |
We simulated the field-dependent magnetization m(H,T) and the uniform susceptibility x(H,T) of classical Heisenberg antiferromagnets in the chain and square-lattice geometry using Monte Carlo methods. The results confirm the singular behavior of x(H,T) at small T,H: limT -> 0 limH->0 x(H,T) = 1/(2J0)(1-1/D) and limH ->0 lim T->0 x(H,T) = 1/(2J0), where D = 3 is the number of spin components, J0 = zJ, and z is the number of nearest neighbors. A good agreement is achieved in a wide range of temperatures T and magnetic fields H with the first-order 1/D expansion results (D.A. Garanin, J. Stat. Phys. 83, 907 (1996)).
