Abstract
Study of magnetostriction of (Lu0.8Ce0.2)2Fe17 has been performed by two methods, bulk and microscopic: by the capacitor dilatometer on a single crystal grown by the Czochralski method and by the X-ray powder diffraction. The field-induced transition from the antiferromagnetic to the ferromagnetic state is accompanied by the lattice expansion both in the basal plane and along the c-axis of the hexagonal structure. In addition to the spontaneous linear magnetostriction λas=0.8Ã10â3, λcs=6.8Ã10â3 along the a and c axes, respectively, and volume effect Ïs = 8.4 Ã 10â3, a comparable field-induced magnetostriction (λa = 1.3 Ã 10â3, λc = 3.4 Ã 10â3, Ï = 6.0 Ã 10â3) is observed in a field of 5 T applied along the a-axis.
