摘要：

Polarized paramagnetic neutron scattering experiments show that persisting ferromagnetic correlations in the FCC stability range of anti-Invar Fe1-xNix alloys with x less than or equal to 0.30 can strengthen with increasing temperature. More clear evidence for this unusual property, and, therefore, for the temperature driven low-spin to high-spin transitions of anti-Invar is provided by paramagnetic scattering experiments on an FCC-stable Fe0.77Ni0.13Mn0.07C0.03 alloy.
