In this work, we suggest the temperatureinduced resistivity change at the martensitic transformation in the NiMnGa ferromagnetic shape memory alloy as a driving mechanism enabling periodic signal generation. We demonstrated its practical importance by a design of the prototype of a lowfrequency autonomous generator. A prominent feature of this new generator is a control of its frequency by the external magnetic field.
