Origin of Interface Magnetism in BiMnO 3 / SrTiO 3 and LaAlO 3 / SrTiO 3

Possible ferromagnetism induced in otherwise nonmagnetic materials has been motivating intense research in complex oxide heterostructures. Here we show that a confined magnetism is realized at the interface between SrTiO3 and two insulating polar oxides, BiMnO3 and LaAlO3. By using polarization dependent x-ray absorption spectroscopy, we find that in both cases the magnetism can be stabilized b...

Superconductivity of SrTiO 3 − δ

Superconducting SrTiO 3−δ was obtained by annealing single crystalline SrTiO3 samples in ultra high vacuum. An analysis of the V (I) characteristics revealed very small critical currents Ic which can be traced back to a unavoidable doping inhomogeneity. R(T) curves were measured for a range of magnetic fields B at I ≪ Ic, thereby probing only the sample regions with highest doping level. The re...

The styrene photocatalytic degradation reaction

In this study the aqueous styrene photocatalytic degradation reaction was evaluated using TiO 2 P-25 (Degussa) as catalyst. The experiments were accomplished in a batch reactor, with temperature control and catalyst in suspension. The radiation source was a 28 W UV lamp. Determinations of styrene concentrations were done by gas chromatography with a flame ionization detector (FID). Preliminary ...

Ab initio calculations of the SrTiO 3 „ 110 ... polar surface

Results of ab initio Hartree-Fock calculations for the SrTiO3 ~110! polar surface are discussed. We have calculated the surface energies, near-surface atomic displacements for four possible terminations ~TiO, Sr, and two kinds of O terminations! as well as Mulliken atomic charges and dipole moments of atoms characterizing their polarization, and the atomic bond populations. We predict a conside...
