摘要：

We have probed the interfacial magnetism between La0.7Sr0.3MnO3 (LSMO) and La0.7Sr0.3CoO3 (LSCO) layers in a [ LSMO(10 u.c.)/LSCO(10 u.c.)] X6 superlattice (SL) using X-ray magnetic circular dichroism and photoemission electron microscopy. Strong magnetic coupling exists between the LSMO and LSCO layers such that the magnetic domains in both layers have similar size and shape, and they flip their magnetization simultaneously. While 10 u.c. LSCO thin films show no evidence of ferromagnetism, the LSCO layer in the superlattice remains ferromagnetic. Such a modification of magnetic properties is proposed to occur due to strong correlations between the layers along the c-axis of the superlattice. (C) 2013 AIP Publishing LLC
