【 摘 要 】
Optical absorption and transverse Kerr effect spectra, resistivity, and magnetoresistance of La1-xSrxCoO3 (x = 0.15,0.25,0.35) films have been studied. The temperature dependences of the optical and magneto-optical properties of the films exhibit features which can be attributed to the transition of the Co3+ ions from the low-spin state (S = 0) to the intermediate-spin state (S = 1) and to orbital ordering of the Co3+ ions in the latter state. The evolution of the properties influenced by doping with Sr is interpreted on the basis of the phase separation model.
