  abstract = {Superlattice structures based on doped Mn-oxides and SrTiO3 exhibit desirable magnetotransport properties, such as an enhanced magnetoresistance (MR) and a broadened MR transition. An La0.7Ca0.3MnO3 (55 Å)/SrTiO3 (160 Å) superlattice shows 61% MR at 0.5 T and 109 K, defined by [R(0 T)-A(0.5 T)]/R(0 T), compared to 38% MR for a single layer La0.7Ca0.3MnO3 film at 125 K. MR of larger than 85% at 5 T has been observed in a broad temperature range (from 150 to 10 K) for this superlattice. A systematic study of La0.7Ba0.3MnO3/SrTiO3 superlattices shows that the decrease of the La0.7Ba0.3MnO3 layer thickness results in the broadening of the MR peak in temperature. © 1997 American Institute of Physics.},
