TL;DR: The magnetic and magnetostrictive properties of Fe/sub 1-x/Ga/sub x/ and Fe sub 1x-y/Al/sub y/ (a+y < 0.3) single crystals were measured under compressive stresses up to 120 MPa and in magnetic fields up to 1 kOe as discussed by the authors.

TL;DR: In this article, a single maximum in the magnetoelastic coupling |b1| of Fe with increasing amounts of nonmagnetic Ga, combined with a strongly temperature dependent elastic shear modulus (c11−c12) is interpreted as anomalous magnetostrictive behavior in Fe-Ga alloys.

TL;DR: In this article, measurements were made of the piezomagnetic d33 coefficient, the free permeability, μ33T, and the open-circuit elastic compliance coefficient, s33H, of grain-oriented Terfenol-D, Tb0.3Dy0.7Fe1.93, produced by a modified Bridgman technique.

TL;DR: The magnetostriction of b.c. Fe is increased over 10-fold at room temperature by the substitution of /spl sim/20% gallium for Fe as mentioned in this paper.

TL;DR: The magnetoelastic energy of rare-earth ions in these compounds is estimated to be 2 to 5 times larger than that of the rare earth elements themselves as discussed by the authors, and the source of the magnetostriction is the large strain-dependent anisotropy of rare earth ion situated at the cubic sites in the $R{\mathrm{Fe}}_{2}$ lattice.
