Abstract

The magnetic structures of a series of Y ₂ (Fe _1-x Mn _x ) ₁₄ B samples, with x equal to 0.03, 0.10, 0.25, and 0.37, have been studied by powder neutron diffraction and Mössbauer spectroscopy. Y ₂ (Fe _0.97 Mn _0.03 ) ₁₄ B and Y ₂ (Fe _0.9 Mn _0.1 ) ₁₄ B are ferromagnetic at both 295 and 85 K, Y ₂ (Fe _0.63 Mn _0.37 ) ₁₄ B is paramagnetic at both 295 and 85 K, whereas Y ₂ (Fe _0.75 Mn _0.25 ) ₁₄ B is paramagnetic at 295 K and is partially ordered at 78 K. The magnetic structure of Y ₂ (Fe _0.75 Mn _0.25 ) ₁₄ B is explained in terms of the preferential Mn occupancy of the transition metal 8j ₂ site in the Y ₂ Fe ₁₄ B structure. Small amounts of Mn located in this site are very effective in disrupting the long-range ferromagnetic coupling.
