| Description |
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-T-c (T-c approximate to 230 K) phase of the compound arises from Mn3+-O-Mn3+ superexchange interactions, whereas in the low-T-c, (T-c approximate to 150 K) phase Mn4+-O-Co2+ superexchange interactions are responsible For the ferromagnetism.
