A significant influence of the magnetic field on the electrical properties during the induction of martensitic transformation, which depends on the influence of the external field and the preliminary thermomagnetic treatment of the samples, was noted. Treatment of Cu-Al-Mn alloy in a magnetic field leads to changes in kinetics and morphology during the induction of phase martensitic transformation. It can be argued that the thermomagnetic treatment of the samples will result in an induced uniaxial magnetic anisotropy or a reduction in the size of ferromagnetic particles. Using the high mechanical properties of Cu-Al-Mn-Fe alloys in combination with the high superparamagnetic properties of Cu-Al-Mn alloys, it is quite possible to use such nanostructured compositions in "smart" devices, the operation of which will be based on the combination of actuator and sensor capabilities.
