Title
Spin fluctuations in an ordered Heisenberg ferromagnet with dipolar interactions
Contributors
S W Lovesey (SERC Rutherford Appleton Lab.)
Abstract
Results from a theoretical analysis of the Heisenberg model of a ferromagnet, including dipolar interactions, are successfully used to interpret recent measurements performed on EuS, just below the critical temperature, that probe the dynamics of long wavelength spin fluctuations parallel (longitudinal) and perpendicular (transverse) to the spontaneous magnetization. Attention is given in the paper to longitudinal fluctuations following this and other related experimental investigations on the topic. With a view to future experiments, properties of the spin dynamics in the critical region are discussed within the framework of the coupled mode approximation.
