Abstract
The nonlinear response of an xy spin chain with anisotropic interaction to an alternating magnetic field polarized along a chosen axis (longitudinal pumping) is considered. The high-frequency magnetization of the system is determined in two limiting cases, namely, a small amplitude of the high-frequency field and a small exchange anisotropy.
