Controlling the coupling between localized spins and itinerant electrons can lead to exotic magnetic states. A novel system featuring local magnetic moments and extended 2D electrons is the interface between LaAlO3 and SrTiO3. The magnetism of the interface, however, was observed to be insensitive to the presence of these electrons and is believed to arise solely from extrinsic sources like oxy...

Pulsed laser deposition (PLD) has been used to grow epitaxially oriented thin films of Cu and Pt on (100)-oriented substrates of both SrTiO3 and LaAlO3. The resulting films have been characterized for their crystalline orientations using x-ray diffraction (XRD) and for their surface morphologies using atomic force microscopy (AFM). The diffraction results illustrated that purely epitaxial Cu(10...

SrTiO3 nanoparticles co-doped with a broad concentration range of Er(3+) and Yb(3+) ions were fabricated using the citric route as a function of annealing temperatures of 500-1000 °C. The effect of a broad co-dopant concentration range and sintering temperature on structural and up-conversion properties was investigated in detail by X-ray diffraction techniques and optical spectroscopy. The TEM...

Pr1−xCaxBa2Cu3O7−δ(x ≈0.5) thin films have been grown on SrTiO3 and YSZ substrates by the pulsed laser ablation. The substrate temperature dependence of orientation and superconducting poperties were systematically studied. Good quality c and a-axis orientated films can be obtained on SrTiO3 via changing the substrate temperature solely. On YSZ, films with good c-axis orientation can be grown, ...

It is pertinent to realize that scientific research indicates the most promising method for producing H2 photo electrochemical water splitting through a anode. Cobalt-doped SrTiO3 (Co-SrTiO3) composite nanostructures were created in this study via hydrothermal synthesis. The impact of cobalt concentration change on Co-SrTiO3 has been identified using morphological, structural, and research. Sur...

Identification of microstructural evolution of nanoscale conducting phase, such as conducting filament (CF), in many resistance switching (RS) devices is a crucial factor to unambiguously understand the electrical behaviours of the RS-based electronic devices. Among the diverse RS material systems, oxide-based redox system comprises the major category of these intriguing electronic devices, whe...

The organic-inorganic composite g-C3N4eSrTiO3:Rh was prepared for the first time as a photocatalyst for hydrogen production and the resulting hydrogen evolution rate under visible light irradiation from aqueous methanol solution was measured. A high hydrogen evolution rate of 223.3 mmol h 1 was achieved by using 0.1 g of as-prepared photocatalyst powder comprised of 20 wt.% g-C3N4 80 wt.% SrTiO...

A study on charge transport properties of thin film Fe-doped SrTiO3 epitaxially grown on Nb-doped SrTiO3 is reported. Electric measurements between 350 °C and 750 °C show a transition from predominant ionic to electronic conduction and lower conductivity of the thin films compared to the bulk of polycrystalline samples. Defect chemical changes at elevated temperature were investigated by applyi...

To date, electric fields have been widely used to control the magnetic properties of BiFeO3-based antiferromagnet/ferromagnet heterostructures through application of an exchange bias. To extend the applicability of exchange bias, however, an alternative mechanism to electric fields is required. Here, we report the photo-control of exchange bias in BiFeO3/La2/3Sr1/3MnO3 thin films on an SrTiO3 s...

– Epitaxial thin films of multiferroic perovskite BiMnO3 were synthesized on SrTiO3 substrates, and orbital ordering and magnetic properties of the thin films were investigated. The ordering of the Mn eg orbitals at a wave vector ( 1 4 1
