摘要：

Crystalline films of La0.65Pb0.35MnO3 grown on (100) LaAlO (3) substrates by rf sputtering have been investigated using magnetic circular dichroism and inverse photoemission spectroscopy. We find evidence for strong hybridization between unoccupied levels associated with Mn 3d and O 2p states. The oxygen atoms "pick-up" a small magnetic moment through hybridization with Mn.
