Magnetically asymmetric interfaces in a LaMnO3/SrMnO3 superlattice due to structural asymmetries
Physical review. B, v 77(17), 174409

Abstract
Polarized neutron reflectivity measurements of a ferromagnetic [(LaMnO3)(11.8)/(SrMnO3)(4.4)](6) superlattice reveal a modulated magnetic structure with an enhanced magnetization at the interfaces where LaMnO3 was deposited on SrMnO3 (LMO/SMO). However, the opposite interfaces (SMO/LMO) are found to have a reduced ferromagnetic moment. The magnetic asymmetry is accompanied by a corresponding asymmetry in the lateral structural roughness of the two interfaces observed via electron microscopy, with enhanced ferromagnetism present at the interfaces that are atomically smooth over tens of nanometers. This result demonstrates that atomic-scale roughness can destabilize interfacial phases in complex oxide heterostructures.
