Spin-phonon coupling effects, as reflected in phonon frequency shifts between ferromagnetic (FM) and G-type antiferromagnetic (AFM) configurations in cubic CaMnO3, SrMnO3, BaMnO3, LaCrO3, LaFeO3 and La2(CrFe)O6, are investigated using density-functional methods [1]. We find that the phonon frequency shifts ∆ω = ωAFM − ωFM strongly depend on the U value when using the DFT+U method. We propose a ...

SrTiO3–LaCrO3 continuous solid solutions with LaCrO3 content ranging from 0.00 to 1.00 were prepared via a polymerized complex method. The light absorption ability of SrTiO3 was improved by the consecutive tuning bandgap upon introduction (up 570 nm). exhibited significantly enhanced photocatalytic activities for H2 evolution under visible irradiation, an optimized rate 1368 μmol h−1 g−1 obtain...

The strong interfacial coupling at the 3d-5d transition metal-oxide interfaces has generated excitement due to possibility of engineering a wide range quantum phenomena and functionalities. Here, we investigate electronic structural properties LaCrO3/KTaO3 heterostructures. High-quality LaCrO3 films were grown on KTaO3 substrates using molecular beam epitaxy. These heterostructures show robust ...
