With the general objective of studying interfaces between ferromagnetic materials and organic semiconductors, we report ac impedance investigations on La0.7Sr0.3MnO3 (LSMO)/tris(8-hydroxyquinoline)aluminum (Alq3)/Al and Indium Tin Oxide (ITO)/Alq3/Al heterostructures, in the frequency range between 20 Hz and 1 MHz. The comparison of the equivalent circuits deduced to fit the experimental ac res...

This study reports the magnetic and cytotoxicity properties of magnetic nanoparticles of La(1-x)Sr(x)MnO(3) (LSMO) with x = 0, 0.1, 0.2, 0.3, 0.4, and 0.5 by a simple thermal decomposition method by using acetate salts of La, Sr, and Mn as starting materials in aqueous solution. To obtain the LSMO nanoparticles, thermal decomposition of the precursor was carried out at the temperatures of 600, ...

At interfaces between complex oxides, electronic, orbital and magnetic reconstructions may produce states of matter absent from the materials involved, offering novel possibilities for electronic and spintronic devices. Here we show that magnetic reconstruction has a strong influence on the interfacial spin selectivity, a key parameter controlling spin transport in magnetic tunnel junctions. In...

We present an exchange bias (EB) effect of variable size in La0.67Sr0.33MnO3−δ single and La0.67Sr0.33MnO3−δ/SrTiO3 (LSMO/STO) bilayers grown on STO substrates. Samples have been prepared by pulsed laser deposition (PLD) and high-pressure sputter deposition (HSD) in oxygen atmosphere at different oxygen pressures. Increased out-of-plane lattice parameters of the LSMO layers and reduced Curie te...

Bi3.25Nd0.75Ti3O12 (BNT) ferroelectric thin films with a thickness of f0.5 Am, on substrates of Pt/Ti/SiO2/Si, (100) SrTiO3 and (100) MgO, with a 0.4-Am-thick La0.7Sr0.3MnO3 (LSMO) layer as bottom electrode, were deposited via pulsed laser deposition. The multilayer thin films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and electrical measurement. The LSMO ...

A dual functional and water soluble spin-coatable lanthanum strontium manganese oxide (LSMO) resist has been developed that consists of lanthanum nitrate, strontium nitrate, manganese nitrate, polyvinyl alcohol and water. Energetic nitrates plus polyvinyl alcohol fuel promote autoignition and produce nanopatterns (<60 nm) upon mild electron beam exposure (<2 mC cm−2). The formation of cubic per...

Appropriately doped perovskite oxides of manganese such as La2/3Sr1/3MnO3 (LSMO) are ferromagnetic metals in which the conduction electrons tend to be 100% spin polarised [5]. It is therefore desirable to fabricate CNT devices with LSMO electrodes. However, to integrate these two very different material systems into a single device is challenging since their growth conditions are potentially mu...

We show a detailed magneto-optical Kerr study at room temperature of well characterized epitaxial La0.7Sr0.3MnO3 (LSMO) thin films grown onto (110) and (11̄8) SrTiO3 substrates. The films present a well-defined uniaxial (two-fold) magnetic anisotropy ascribed to substrate-induced anisotropy. In particular, the in-plane uniaxial anisotropy in the(110)-oriented LSMO films originates from the exist...

The inorganic/molecular spinterface is an ideal platform for generating extraordinary spin effects. Understanding and controlling these spin-related effects mandatory the exploitation of such interfaces in devices. For this purpose we have investigated adsorption α-sexithiophene (α-6T) on La0.7Sr0.3MnO3 (LSMO) as one prototypical material combinations used organic spintronic Atomic force micros...
