The magnetization of face-centred cubic and body-centred cubic iron + nickel alloys

Source abstract

Abstract Magnetizations of single phase binary iron + nickel alloys have been measured and Bohr magneton numbers p estimated for body-centred cubic alloys with 0 to 32.3 at. % of nickel and for face-centred cubic alloys with 31 to 80 %. Initially p increases at the rate 1.1 ±0.1 μB per nickel atom in iron-rich b.c.c. alloys. In the f.c.c. phase p increases as the nickel content decreases, and then falls very sharply as the nickel content further decreases below 40 %. In the small range of composition where either phase can be obtained, the magnetization differs widely between the two crystal structures.
