摘要：

A possible origin is proposed on the anomalous optical absorption which is observed in ferromagnetic metal La1-xSrxMnO3. It is argued that the interband transition within e(g) orbitals is responsible for the absorption. The orbital dependence of transfer integrals is crucial to make the transition allowed.
