Abstract

Study of magnetostriction of (Lu_0.8Ce_0.2)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 λ_a^s = 0.8 × 10^{- 3}, λ_c^s = 6.8 × 10^{- 3} along the a and c axes, respectively, and volume effect ω_s = 8.4 × 10^-3, a comparable field-induced magnetostriction (λ_a = 1.3 × 10^-3, λ_c = 3.4 × 10^-3, ω = 6.0 × 10^-3) is observed in a field of 5 T applied along the a-axis.
