چکیده انگلیسی
Inelastic neutron scattering experiments were performed on an intermetallic compound, MnP. We used a newly developed High Resolution Chopper Spectrometer, HRC, for energy transfers Eâ¤75meV, besides various triple axis spectrometers; LTAS for energy transfers Eâ¤2meV, TOPAN for Eâ¤7.5meV and TAS-1 for Eâ¤35meV. Spin wave excitations were observed in the ferromagnetic phase of MnP in the entire Brillouin zone along the aâ- and bâ-axes. The zone boundary energies of spin waves were determined to be around 60 meV along the aâ-axis and around 75 meV along the bâ-axis, and the dispersion relations showed two branches for both axes. The observed dispersion relations of spin waves were well described by an isotropic Heisenberg interaction adding a single ion anisotropy with two sub-lattices.
