Abstract
- Structural, magnetic, and magnetocaloric properties of DyNi 0.67 Si 1.34 were investigated using X-ray powder diffraction, magnetic susceptibility, and magnetization measurements. X-ray powder diffraction pattern shows that DyNi 0.67 Si 1.34 crystallizes in the AlB 2 -type hexagonal structure (space group: P 6/ mmm , No. 191, a = b = 3.9873(9) A, and c = 3.9733(1) A). The compound is a spin-glass with the freezing temperature T G = 6.2 K. The ac magnetic susceptibility measurements confirm magnetic frustration in DyNi 0.67 Si 1.34 . The maximum value of the magnetic entropy change determined from M(H) data is −16.1 J/kg K at 10.5 K for a field change of 70 kOe.
