Autostabilization Of Temperature In Systems With Combined Magnetic And Resistive Transition Under Electric Current Flow

It is shown that the active thermostabilization regime can be realized in systems based on materials exhibiting combined magnetic and resistive phase transition of first order, when the sample temperature under electric current is self-maintained about the threshold equal to T-c (T-c is the phase transition temperature). The dependences of the ferromagnetic phase fraction as well as the sample temperature on the electric and magnetic field have been calculated. The system working parameters necessary to realize the active thermostabilization regime have been determined. It is found that the magnetic field can effectively influence the system temperature under certain circumstances.
