Negative Thermal Expansion in Ferromagnetic Fe-Ni Invar Alloys

The INVAR effect in 3D-transition metal Fe1-xNix alloys with x=0.35, 0.50,0.70 is studied.Experiments have been made on thermal and structural properties to study the physical origin of INVAR characteristics such as thermal expansion atomic ordering, phase transition an...
