We investigate resonance phenomena in a system consisting of a nanomagnet coupled to a Josephson junction under external periodic drive. The coupling in the system leads to the appearance of additional resonance peaks whose properties depend on the periodic signal and Josephson junction dynamics. In the linear regime, we derive an analytical description of the resonance phenomena which are then confirmed by numerical simulations. This analytical method is universal and can also be applied to Josephson junctions with an anomalous phase shift in the current phase relation. This work provides a method for controlling the resonances of hybrid structures that might be interesting for applications.
