METHOD FOR OBTAINING MATERIAL WITH MAGNETOCALORIC EFFECT GIANT BY IRRADIATION OF IONS

摘要

The present invention relates in particular to a process for obtaining a magnetocaloric effect product from an integral material having a magnetic phase transition, the process comprising irradiating at least a portion of the material with ion, the irradiation being conducted with a fluence adapted so that the material has, after irradiation, different magnetic phase transition temperatures in different parts of the material.
