Manipulating magnetic anisotropy (MA) purposefully in transition metal oxides (TMOs) enables the development of oxide-based spintronic devices with practical applications. Here, we report a pathway to reversibly switch lateral easy-axis via interfacial oxygen octahedral coupling (OOC) effects 3d-5d tricolor superlattices, i.e. [SrIrO3,mRTiO3,SrIrO3,2La0.67Sr0.33MnO3]10 (RTiO3: SrTiO3 and CaTiO3...

We present a method for increasing the dielectric constant of CaTiO3/CaCu3Ti4O12 (CTO/CCTO) composites and retaining low-loss tangent (tan?) by doping with Ge dopant. The Ge-doped CTO/CCTO were fabricated using one-step processing method. phase composition microstructure analyses confirmed existence CTO CCTO phases, in which ions can be substituted into both phases. mean grain sizes two phases ...

In the survey of photoluminescence properties of rare-earth doped alkaline-earth stannates, CaSnO3 was found to show intense white luminescence by Pr doping and green luminescence by Tb-Mg codoping. Pr-doped CaSnO3 showed not only a red emission line originating from the f-f transition from D2 to H4 state, which is observed in Pr doped CaTiO3 or SrTiO3, but also an intense blue-green line assig...

Aims. To trace the source of the unique 13, 19.5, and 28 μm emission features in the spectra of oxygen-rich circumstellar shells around AGB stars, we have compared dust extinction spectra obtained by aerosol measurements. Methods. We have measured the extinction spectra for 19 oxide powder samples of eight different types, such as Ti-compounds (TiO, TiO2, Ti2O3, Ti3O5, Al2TiO5, CaTiO3), α-, γ-,...

The optimized-effective-potential method is a special technique to construct local Kohn-Sham potentials from general orbital-dependent energy functionals. In a recent publication [M. Betzinger, C. Friedrich, S. Blügel, A. Görling, Phys. Rev. B 83, 045105 (2011)] we showed that uneconomically large basis sets were required to obtain a smooth local potential without spurious oscillations within t...
