Geometric tuning of charge and spin correlations in manganite superlattices
Geometric tuning of charge and spin correlations in manganite superlattices
We report a modulation of the in-plane magnetotransport in artificial manganite superlattice [(NdMnO3)n/(SrMnO3)n/(LaMnO3)n]m by varying the layer thickness n while keeping the total thickness of the structure constant. Charge transport in these heterostructures is confined to the interfaces and occurs via variable range hopping. Upon increasing n, the interfacial separation …
