Spin-wave dispersion relation in partially ordered Ni3Mn
The spin-wave dispersion relation of partially ordered Ni3Mn has been measured in the \111\ direction by inelastic neutron scattering experiments using the triple-axis technique. The dispersion curve rises quadratically according to the relation h omega = Dq2 and the stiffness constant D is about se...

| Zusammenfassung: | The spin-wave dispersion relation of partially ordered Ni3Mn has been measured in the \111\ direction by inelastic neutron scattering experiments using the triple-axis technique. The dispersion curve rises quadratically according to the relation h omega = Dq2 and the stiffness constant D is about seven times greater than the D value estimated for the disordered (quenched) alloy.10 refs.--AA |
