摘要：
With the use of self-consistent spin-wave theory, the spin stiffness for the two-dimensional classical easy-plane ferromagnet is calculated. The Kosterlitz-Thouless transition temperature for the classical XY model is obtaind. The contribution of vortex-antivortex bound pairs to the central peak at low temperatures is discussed.
