Abstract

Typical ferromagnets elongate and contract anisotropically when placed in a magnetic field but conserve the overall volume, an effect known as Joule magnetostriction; here, a new effect is observed in Fe–Ga alloys—large non-volume-conserving or non-Joulian magnetostriction—which has not previously been observed in any magnet.
