Abstract
The homogeneity region at 650 °C of compounds Mn1+xSb1-ySny with the NiAs (B 8)-type structure was determined from X-ray crystallographic data. A complete series of solid solutions was found between y = 0 and y = 1, with x changing gradually from x = 0-0.2 for y = 0 to x = 0.6-0.8 for y = 1. Measurements of the magnetization and the magnetic susceptibility of Mn1+xSb1-ySny, show a strong variation of the magnetic properties with composition. Neutron diffraction data of Mn1,15Sb show two magnetic sublattices ; the moments of Mn on octahedral sites (3.65 ± 0.07 µB at 4.2 °K) are antiparallel to the moments of Mn on the interstitial, trigonal-bipyramidal sites (3.0 ± 0.4 µB at 4.2 °K)Keywords
