Abstract

We report spin-wave results for the sublattice magnetization (to order O(1/S²)) and two spin stiffnesses and susceptibilities (to order O(1/S)) for the two-dimensional triangular Heisenberg antiferromagnet. These stiffnesses and susceptibilities are used as input parameters in scaling functions for various observables. The scaling results for uniform susceptibility are compared with recent numerical data.
