Abstract

Neutron diffraction studies were made of the magnetic structure and spin wave excitations in a single-domain crystal of intermetallic compound MnNi. It was shown that the magnetic moments of manganese atoms are arranged in (001) planes and are oriented along [110] direction. Spin wave velocities are not significantly different from those in a number of γ-Mn alloys in spite of very high Néel temperature of MnNi and the energy gap, if any, is not bigger than 3 meV
