抄録

Magnetization measurements and ⁵⁵Mn NMR study of a system with the nominal formula LaNi_1−xMn_xO₃ (0.0≤x≤0.5) were made. It was found that materials with 0.03≤x≤0.5 are mixtures of a Pauli paramagnet LaNiO₃ and a ferromagnet LaNi_0.5Mn_0.5O₃. The Curie temperature of LaNi_0.5Mn_0.5O₃ was found to be 275 K. In this material, strong ⁵⁵Mn NMR signals associated with Mn⁴⁺ were observed. The observed hyperfine magnetic fields are about −260 kOe, which is considerably smaller than the ones observed for the Mn⁴⁺ ions in other oxides. This smallness of the value seems to be due to the supertransferred hyperfine magnetic fields from the neighboring Ni²⁺ ions.
