Abstract
Core-level Mn and Co 2p X-ray photoelectron spectroscopic studies give evidence for different spin states of Mn and Co in the two different phases of the ferromagnetic compound LaMn0.5Co0.5O3. Ferromagnetism in the high-Tc (Tc≈230 K) phase of the compound arises from Mn3+-O-Mn3+ superexchange interactions, whereas in the low-Tc (Tc≈150 K) phase Mn4+-O-Co2+ superexchange interactions are responsible for the ferromagnetism.
