Abstract
SynopsisInvestigation on modifications of structural and magnetic properties of magnetocaloric thin films induced by slow highly charged ions bombardment under well-controlled conditions is presented. The ions induce defects/constraints that facilitate nucleation of one phase with respect to the other in the first-order magnetostructural MnAs, with a consequent suppression of thermal hysteresis, but without any significant perturbation on the other structural and magnetic properties.

Data obtained refrigerator systems is blocked by the presence by a temperature increase of a large thermal hysteresis in the magnetization cycle, which is typical of firstand decrease are presented in blue and red, respectively
From other technics applied previously to reduce the thermal hysteresis [3,4,5], ion collisions induce defects that act as seeds for the nucleation of one phase with the other during the transition
