_{3}multiferroic single crystal manganites were measured in magnetic field. From the specific heat data it was stated that the effect of dilution of Mn by non‐magnetic Ga

^{3+}ions led to reduced Mn magnetic interactions and suppressed the magnetic ordering of Yb in both the 2

_{12}garnet (LuAG) removes the electron trapping associated with cation antisite defects. In this paper, we show via atomic scale simulations that the replacement of Al with Ga in LuAG actually lowers the energy of the antisite disorder process. Thus, we predict that Ga additions will lead to an increase of the antisite defect concentration...

_{2}S was studied with fluorescence spectroscopy. It is shown that temperature quenching of Ce

^{3+}ion fluorescence is due to high‐order multiphonon relaxation. The direct evidence of spatial confinement effect in multiphonon relaxation was obtained: relaxation is more efficient in nanoparticles than in micron‐sized particles.

_{3}(LSMO/STO) (001) interfaces are considered by performing generalized gradient approximation plus on‐site Coulomb correction calculations. A potential antiferromagnetic alignment between the interface layer and bulk is conjectured for the b‐type LSMO/STO (001) interface where the atomic‐layer stacking near...

**215–232**) is focused on transport phenomena in topological insulators. This novel class of materials is distinct from conventional band insulators and conductors by the topologically nontrivial band structure that gives rise to unusual transport properties. In a topological insulator the character of electron transport varies from insulating...
