Weak Ferromagnetism in LaCo1-xRhxO3: Anomalous Magnetism Emerging between Two Nonmagnetic End Phases

Magnetization has been measured for polycrystalline samples of LaCo 1- x Rh x O 3 (0 ≤ x ≤0.9) in order to investigate the magnetism induced in the solid solution of two nonmagnetic end phases of LaCoO 3 and LaRhO 3 . It is found that a ferromagnetic transition is observed below 15 K in the x range from 0.1 to 0.4. The effective Bohr magnetic moment evaluated from the temperature dependence of magnetic susceptibility at around room temperature is independent of x for 0 < x < 0.5 (approximately 3 µ B per formula unit), and rapidly decreases above x = 0.5. On the basis of detailed magnetization measurements, the spin state and magnetic ordering of LaCo 1- x Rh x O 3 are discussed.
