The study of caloric effects in magnetic materials with phase structural transitions occurring over a wide temperature range, in particular in Heusler alloys, has a great interest of applications in the area of solid-state cooling. The elastocaloric effect was investigated theoretically in this work on the example of Heusler alloys, taking into account the motion of the domain wall of the magnetostructural transition. It is shown, that in the presence of a cyclic action by an external field of mechanical stresses in the adiabatic regime and a transition through the critical region of the phase magnetostructural transition, a maximum of the amplitude of temperature oscillations occurs. The modes of heat transfer promising for organizing cooling cycles in a wide temperature range including the cryogenic region are demonstrated.
Keywords: Heusler alloy, elastocaloric effect, structural order parameter, austenitic and martensitic phases.
