Abstract
A FeRh thin film of 33 nm thickness grown by molecular beam epitaxy (MBE) has been investigated with respect to its temperature dependent magnetic properties by means of ferromagnetic resonance (FMR). Within the ferromagnetic regime, i.e. at temperatures above the antiferromagnetic-to-ferromagnetic phase transition, the resonance field decreases with decreasing temperature reflecting an increasing magnetization. Within the temperature regime of the phase transition, the resonance field behaves non-monotonically, i.e. it suddenly increases with decreasing temperature. The observed asymmetric shape of the FMR absorption line is discussed with respect to a possible small magnetic inhomogeneity of the film coupled to the main ferromagnetic volume of B2 ordered, equiatomic FeRh.
