摘要：

Spin excitations in a single crystal of the Laves phase compound HoCo2 have been studied using inelastic neutron scattering. At 4 K three modes are observable: an in-phase spin precision acoustic mode and two out-of-phase optic modes involving the rare earth spins. A self-consistent Green's function RPA theory has been used to analyze the data and obtain exchange and crystal field parameters. © 1979.
