Magneto Structural Studies on Gadolinium-Iron Alloys

Magnetic and constitutional data have been established for a series of alloys in the gadolinium-iron system, ranging from 2–98% Fe. Seven intermetallic compounds have been found and some correlation has been derived between their crystal structures and magnetic properties. The cubic ${\mathrm{Gd}}_2{\mathrm{Fe}}_3$ compound has been found to exhibit highest magnetization values of the intermetallics and comparison of data on the Gd-Co and Gd-Ni compounds suggests that presence of the 2:3 structure (not found in the Gd-Ni system) is necessary for the development of ferromagnetism in these systems.
