... Russia Abstract Hydrides of the intermetallic compound Mn 3 Sn have been prepared at 3508C and pressures of molecular hydrogen between 2.8 and 4.0 119 Ё GPa. The hydrides with an approximate composition Mn 3 SnH were found to have a cubic perovskite structure. ... Discussion The temperature dependence of the average 119 Sn hyperfine fields clearly indicates that a transition between different magnetic states occurs in the Mn 3 SnH x hydrides. ... The same holds for the hydrogen atoms on 1b sites. ...
