Properties of magnetic damping in the FeRh alloy are determined by stoichimetric ratio of individual components of the alloy, by the number of structural defects, and rate of epitaxy of thin films deposited on MgO(001) substrates. This thesis describes the mechanism of each contribution to magnetic damping and clarifies the influence of stoichimetric ratio, structural defects, and epitaxy on the resulting magnetic damping. FeRh thin films were deposited using magnetron sputtering and characterized via vibrating sample magnetometry. Magnetic damping was evaluated using broadband ferromagnetic resonance. The magnetic damping significantly increases with increasing amount of Rh atoms in the alloy, decreasing rate of epitaxy, and increasing number of structural defects.
