The ferroelectric ordering temperatures are observed at much higher temperatures than their corresponding magnetic ordering temperatures for all the members.

Detailed superconducting quantum interference device measurements reveal a complex phase diagram with five distinct magnetic phases.

The temperature dependence (10–300 K) of the radial distribution function (RDF) for the Mo–O atom pairs in the first coordination shell of molybdenum atoms is reconstructed by the regularization-like method from the experimental EXAFS spectra.

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.

Especially the origin of multiferroic or magnetoelectric effects may be hard to ascertain as the related displacements can reach the detection limit [...] OpenAccess: PDF PDF (PDFA); 2018-01-2212:32 [PUBDB-2018-00717] Journal Article et al Raman and fluorescence contributions to the resonant inelastic soft x-ray scattering on $LaAlO_{3}/SrTiO_3$ heterostructures Physical review / B 97(3), 035110 (2018) [10.1103/PhysRevB.97.035110]   We present a detailed study of the Ti $3d$ carriers at the interface of $LaAlO_{3}/SrTiO_3$ heterostructures by high-resolution resonant inelastic soft x-ray scattering (RIXS), with special focus on the roles of overlayer thickness and oxygen vacancies. Our measurements show the existence of interfacial Ti $3d$ electrons already below the critical thickness for conductivity [...] OpenAccess: PDF PDF (PDFA); 2018-01-1211:04 [PUBDB-2018-00603] Journal Article et al Characterization of $\mathrm{A^{III}B^V}$ superlattices by means of synchrotron diffraction topography and high-resolution X-ray diffraction Journal of applied crystallography 50(4), 1192 - 1199 (2017) [10.1107/S1600576717008846]   New possibilities are presented for the characterization of A$^{III}$B$^V$ mixed superlattice compounds by the complementary use of synchrotron diffraction topography and rocking curves. In particular, using a synchrotron white beam and the section diffraction pattern of a 5 µm slit taken at a 10 cm film-to-crystal distance, it was possible to reproduce a set of stripes corresponding to interference fringes.

Structural insight into the interacting surfaces is a prerequisite to understand the interaction characteristics as well as the underlying physical mechanisms. [...] Published on 2017-02-09.
