Abstract

The compound Dy₅Si₂Ge₂ crystallizes in an orthorhombic structure (Sm₅Ge₄ type, space group Pnma). Magnetization measurements performed in the temperature range of 2-300 K in applied fields up to 7 T reveal that this compound orders antiferromagnetically at 56 K (T_N) but with a positive paramagnetic Curie temperature θP. Magnetization-field isotherms, obtained at 5 K and 20 K, display a field-induced antiferromagnetic to ferromagnetic transition. the magnetization approaches saturation in a field of 6 T with a moment value of ~8μ_BDy³⁺. Neutron diffraction measurements, carried out at 9.2 K, suggest that Dy moments arrange spirally along an axis giving rise to a canted antiferromagnetic structure. the analysis of neutron diffraction data yields an ordered state magnetic moment of 7.63μ_B per Dy³⁺ ion. © 2005 American Institute of Physics.
