SrRuO3–SrMnO3 multilayers with heterointerfaces of similar inversion symmetry were fabricated. The SrTiO3/[SrMnO3/SrRuO3]15 multilayer shows lower Curie temperature, smaller magnetization and larger magnetoresistance compared to SrTiO3/[SrRuO3/SrMnO3]15 multilayer. The variations of these properties with the inversion of stacking order are well correlated with each other which occur due to pinned/biased moments and can be explained by their cumulative stress difference.

    Manganites, as La1-xSrxMnO3, are known as ferromagnetic materials, with a "bad metal" behavior, and a transition temperature close to Curie temperature. The manganites with La0.54Ho0.11Sr0.35Mn1-xVxO3 were prepared by means of sol-gel methods. The treated samples were monitorized by XRD, while...

    We report on an enhancement of the Curie temperature in GaMnAs/InGaMnAs superlattices grown by low-temperature molecular beam epitaxy which is due to thin InGaMnAs or InGaAs films embedded into the GaMnAs layers. The pronounced increase of the Curie temperature is strongly correlated to the In...

    La, Sr, Mn, and Mg precursors were mixed in stoichiometric ratio 0.67/0.33/1/x with solvent and were spin-coated onto (001) LaAlO3 substrates. X-ray diffraction and elemental mapping of these films indicate that for small addition of Mg precursor, Mg2+ acts as a dopant in La0.67Sr0.33MnO3 phase...
