摘要：

A profile analysis of the neutron diffraction spectrum of the fee high pressure hydride gamma-MnH(0.41) measured under ambient conditions showed that hydrogen is randomly distributed over the octahedral interstices of the fee metal lattice and that the hydride is an antiferromagnet with the same collinear spin structure as pure gamma-Mn, but with a smaller magnetic moment of about 1.9 Bohr magnetons per Mn atom.
