Crystal structure and magnetic properties of Lu2Co17-xSix single crystals
Result description
Single crystals of Lu2Co17-xSix within the homogeneity range of Si substitution for Co (0 x 3.4) were grown by the Czochralski method. Magnetization measurements have revealed that the parent Lu2Co17 compound has a spin-reorientation transition (SRT) from the easy plane to the easy axis at elevated temperatures which occurs as two second-order phase transitions, the ?plane-cone at TSR1 670 K and the ?cone-axis at TSR2 730 K. In Lu2Co16Si, the SRTs shift towards lower temperatures (TSR1 75 K, TSR2 130 K)and disappear for compounds with Si content x > 1 where the anisotropy is uniaxial over the whole range of magnetic ordering. A phenomenological discussion of Co-sublattice anisotropy, with reference to the model of individual site contribution to magnetic anisotropy (ISA) is provided.
