High-field magnetostriction measurements on Fe/sub 14/Nd/sub 2/B magnets

OSTI ID:6544741

Magnetostriction measurements have been made on aligned polycrystalline Fe/sub 14/Nd/sub 2/B magnets from two US manufacturers at applied fields up to 144 kOe at room temperature. The ordinary magnetostriction is comparable to that of iron (10 x 10/sup -6/). The high field forced magnetostriction is positive for all orientations of the field and of the measured strain, strongly anisotropic, and similar in magnitude to normal ferromagnetic materials. The forced volume magnetostriction is 1.3 x 10/sup -9/ Oe/sup -1/ with the field parallel to the alignment axis, and 2.1 x 10/sup -9/ Oe/sup -1/ with the field perpendicular.
