Abstract

Measurements of AC-susceptibility versus temperature curves were made in thin plates of both ordered and disordered Fe-28.3at.%Pt invar alloys before and after swift heavy ion irradiation. In disordered Fe-Pt invar alloy the Curie temperature decreased about 15 K by the irradiation of 200 MeV Xe-ions to the fluence of 10¹⁴ ions/cm². In ordered Fe-Pt invar alloy the Curie temperature decreased about 128 K to the value just coincide with that of irradiated disordered alloy. By comparing these data to the previous one for Fe-Ni invar alloys, it was concluded that there exist at least two mechanisms having opposite contribution.
