The crystalline structure, anisotropic magnetoresistance (AMR), andmagnetization of La0.7Sr0.3MnO3/SrTiO3 (LSMO/STO) superlattices grown by an rfsputtering system are systematically analyzed to study the spin polarization ofmanganite at interfaces. A perfectly epitaxial growth with sharp interfacesbetween LSMO and STO layers is confirmed by the transmission electronmicroscopy (TEM) image and the x-ray diffraction. The presence of positivelow-temperature AMR in LSMO/STO superlattices with thinner LSMO layers orthicker STO layers implies that two bands of majority and minority charactercontribute to the transport properties, leading to a reduced spin polarization.Furthermore, the magnetization of superlattices follows the T3/2 law at lowtemperatures and decays more quickly as the thickness ratio dSTO/dLSMOincreases, corresponding to a reduced exchange coupling. The results clearlyshow that the spin polarization is strongly correlated with the influence ofinterface-induced strain on the structure.Comment: 21 pages, 5 figure
