In order to comprehend the electronic structure across the $LaAlO_3-SrTiO_3$ oxide interface, a detailed valence band investigation has been carried out using variable energy hard X-ray photoelectron spectroscopy and signatures of both low-energy coherent and high-energy features have been observed in the valence band spectra.

Stishovite, the tetragonal rutile‐type polymorph of SiO$_2$, distorts to an orthorhombic CaCl$_2$‐type structure at pressures and temperatures of the lower mantle [...] 2018-10-1811:12 [PUBDB-2018-03830] Journal Article et al Signature of a highly spin polarized resonance state at $\mathrm{Co_{2}MnSi(0 0 1)/Ag(0 0 1)}$ interfaces Journal of physics / D Applied physics D 51(13), 135307 (2018) [10.1088/1361-6463/aab1cf]   We investigated interfaces of halfmetallic Co$_2$MnSi(1 0 0) Heusler thin films with Ag(1 0 0), Cr(1 0 0), Cu and Al layers relevant for spin valves by high energy x-ray photoemission spectroscopy (HAXPES). Experiments on Co$_2$MnSi samples with an Ag(1 0 0) interface showed a characteristic spectral shoulder feature close to the Fermi edge, which is strongly diminished or suppressed at Co$_2$MnSi (1 0 0) interfaces with the other metallic layers [...] Restricted: PDF PDF (PDFA); 2018-07-1614:59 [PUBDB-2018-02622] Journal Article et al $CrO_{4}$ distortion-driven ferroelectric order in $(R, Y) CrO_{4} (R=Sm , Gd, and Ho)$: A new family of multiferroics Physical review / B 98(1), 014408 (2018) [10.1103/PhysRevB.98.014408]   We report a new multiferroic family of $(R,Y)CrO_4(R=Sm,Gd,$ and $Ho)$.

The hysteretic behavior has been evidenced from the tempera-ture dependence of the pre-edge shoulder intensity at the Mo K-edge, indicating that the transition from brownish-red γ-CuMoO$_4$ to green α-CuMoO$_4$ occurs in the temperature range of 230–280 K upon heating, whereas the α-to-γ transition occurs between 200 and 120 K upon cooling.
