Engineering of long range coupling in manganate superlattices by design of spacer layer.
Interfaces made of strongly correlated oxides have shown unexpected physical properties, such as the exchange bias, proximity effects, charge transfer, spontaneous mangetic reversal, exchange springs and orbital reconstruction. Given the complexity of its structural and magnetic phase diagram, LSMO offers a wide range of tunable properties that we can stack into heterostructures. We synthesized all manganate superlattices with a large gradient in hole doping by tuning the Sr-doping layer-by-layer. In previous PNR experiments, we observed a doubled non-collinear magnetic structure at intermediate spacer thickness, temperature and fields. We believe that this non-collinear magnetic phase is linked to the presence of highly canted spins at the interfaces. The aim of this proposal is to understand the magnetic nature of the spacer by a comparative study of SLs and single layer LSMO of different Sr-doping. This study will help to shed light on the role of the spacer magnetic ordering in the formation of the global doubled magnetic structure.
