Abstract

Magnetization was measured on single crystals U2(Fe 1-xCox)13.6Si3.4 (0≤x≤1) grown by Czochralski method. Compounds with x up to 0.95 exhibit the easy-plane magnetic anisotropy. The anisotropy constants K1 and K2 for x up to ∼0.8 are high enough to suggest a U contribution to the anisotropy, i.e., a magnetic state of U. Both K1 and K 2 behave non-monotonously with increasing x, K2 changes sign at x=0.3. We suppose that U becomes non-magnetic above x=0.9. The weakening of the anisotropy and the change of its type at high Co content are attributed to the 3d-metal sublattice.
