Abstract
Thermal relaxation is taken into account in analysis of the reversible transverse susceptibility (RTS) of an interacting particulate system described within the mean-field approximation. Particle orientation is given by a texture function with independent in-plane and out-of-plane components. The shape and location of the RTS peak at coercivity critically depends on temperature, texture, and on the interaction strength while the peak at the anisotropy field gradually merges with the coercivity peak at a strong-coupling field. There are only two peaks remaining in RTS measurement for either a strongly coupled or a well-aligned system. Thus, peak-detection techniques fail to distinguish the anisotropy field and coercivity.
