Abstract

The perovskite-type oxides R_xSr_1-xCoO₃ (R = La, Pr, Ho) have been studied by means of neutron-diffraction and magnetic susceptibility measurements. A ferromagnetic transition occurs in La_0.4Sr_0.6CoO₃ and Pr_0.2Sr_0.8CoO₃ at T_c ∼ 260 K (M = 1.84μ_B) and 175 K (M = 1.29 μ_B), respectively. No magnetic transition was observed in the Ho-doped compound. Inelastic neutron scattering has been employed to study the crystalline-electric-field (CEF) interaction in these compounds. We have succeeded in reproducing the observed energy spectra using CEF parameters required for cubic symmetry.
