Abstract
Thermal expansion measurements as a function of temperature and magnetic field were carried out on Fe-Ni-Cr and Fe-Ni-Mn alloys. The magnetic contribution to the thermal expansion was determined with respect to the paramagnetic reference samples in the Fe-Ni-Cr and Fe-Ni-Mn series. We observe a general behavior that alloys which order ferromagnetically show a positive magnetovolume effect which persists to temperatures much higher than the Curie temperature, whereas in the case of antiferromagnetic ordering the magnetovolume effect is positive below temperatures slightly higher than the Néel temperature, and negative above it.This publication has 3 references indexed in Scilit:
