Abstract

The magnetic properties of single crystalline Fe₂GeS₄ and Mn₂SiS₄ with the olivine structure were investigated. In Fe₂GeS₄, the first-order phase transition at 69 K was confirmed to involve a spin reorientation from the b- to the a-axis with decreasing temperature. As for Mn₂SiS₄, the emergence of weak feiromagnetism near the Néel temperature (T_N) was attributed to the steep suppression of the spin-flop field around T_N. The role of thermal fluctuations is stressed.
