Thermoremanence anomaly in Fe-Zr(B,Cu) Invar metallic glasses: Volume expansion induced ferromagnetism Hernando Grande, Antonio Crespo del Arco, Patricia Castaño, F. J. Arcas, J. Multigner, M. Barandiarán, J. M. Fernández Barquín, L. 538.9 Amorphous Fe-Zr Magnetic-properties Alloys Transition Fe_(90)Zr_(10) State Física de materiales Física del estado sólido 2211 Física del Estado Sólido ©2000 The American Physical Society We report the existence of a thermally induced sharp increase of thermoremanence around the Curie temperature of Invar-like Fe-Zr(B,Cu) soft magnetic glasses. Neutron-diffraction measurements indicate that a true enhancement of the average local magnetic moment, rather than only a change in the domain structure, occurs. Such enhancement has been tentatively attributed to the increasing volume expansion that takes place beyond the Curie temperature and reinforces ferromagnetism in some low-density clusters.
