Epitaxial La 0.67 Sr 0.33 Mn O 3 ∕ La 0.67 Ba 0.33 Mn O 3 superlattices
Artificially layered superlattices allows manipulation of strain and the study of dimensional crossover by introducing additional degrees of freedom not found in bulk materials. Superlattices of the colossal magnetoresistive materials, La 0.67 Sr 0.33 Mn O 3 (LSMO) and La 0.67 Ba 0.33 Mn O 3 (LBMO)...
