This article describes the static, dynamic, and temperature dependent magneto-transport properties of Fe/BTO/LSMO mutliferroic tunnel junction (MFTJ). The multilayer structure is grown on a high quality crystalline STO substrate by means pulsed laser deposition, which enables epitaxial layer-by-layer growth. MFTJ patterned into micrometer-size devices ion-etching-free lithography process ensuri...

Perovskites form a class of promising materials for the development of multifunctional devices but require reliable strategies for forming electrical contacts without compromising functionality. We explore the interactions of a range of metal contacts with ferromagnetic oxide La0.7Sr0.3MnO3 (LSMO) and discuss their impact on the magnetic, structural, and chemical properties of the oxide. Althou...

Introduction Due to spin, lattice and orbital coupling, manganese-based La1-xSrxMnO3 (LSMO) compounds exhibit unusual physical properties, such as colossal magnetoresistance and almost total spin polarization (95% at 4 K) at the composition x = 0.33 [1]. Thus, La0.67Sr0.33MnO3 has significant potential for applications in spintronic devices such as magnetic field sensors, networked environmenta...

Strain-engineering is used as a tool to alter electronic and magnetic properties like anisotropy energy. This study reports the different angle-dependent magnetoresistance of strain-engineered La0.67Sr0.33MnO3 (LSMO) thin films, grown on LaAlO3, compared their bulk analogs. Upon increasing temperature, symmetry change from fourfold [cos(4θ)] twofold [cos(2θ)] observed in resistance measurements...

Bi 0.89 Ho 0.08 Sr 0.03 Fe 0.97-x Mn Ni a/b O 3 /La 0.7 0.3 MnO (BiFeO -Ni /LSMO), (Ni , a≠b a, b ∈ x, x = 0.01–0.04) films were successfully prepared by the wet chemical method. The results show that change of structure makes interface conductivity upper layer and bottom different, which in difference polarization. Ferroelectric polarization leads to changes thickness depletion height barrier,...

The relatively low magnetocrystalline anisotropy (MCA) in strongly correlated manganites (La,Sr)MnO_{3} has been a major hurdle for implementing them in spintronic applications. Here we report an unusual, giant enhancement of in-plane MCA in 6 nm La_{0.67}Sr_{0.33}MnO_{3} (LSMO) films grown on (001) SrTiO_{3} substrates when the top 2 nm is patterned into periodic stripes of 100 or 200 nm width...

A revisited study of perovskite-based manganite La0.67Sr0.33MnO3 (LSMO) deposited onto corning-glass (CG) substrates is reported here. The LSMO films were fabricated with RF sputtering different deposition times, varying from 60 to 180 min, resulting in thicknesses 35.0–109.7 nm. Rietveld refinements the XRD spectrum showed that samples exhibited hexagonal structures a space group R-3c (167) an...
