First-principles study of rare-earth oxides
TL;DR: In this article, the authors used self-interaction-corrected local spin density (SIC-LSD) approximation to describe the electronic structure of dioxides and sesquioxides.

Adsorption and Decomposition of NO on Lanthanum Oxide
TL;DR: The adsorption behavior of NO on La2O3, an effective catalyst for selective NO reduction with CH4 at temperatures above 800 K, depends upon the pretreatment as indicated by temperature-programmed desorption (TPD) and diffuse reflectance FTIR spectroscopy (DRIFTS) as discussed by the authors.

Ab initio calculation of the crystal structure of the lanthanide Ln2O3 sesquioxides
TL;DR: In this paper, density functional theory was employed to calculate the equilibrium crystal lattice dimensions for most of the rare-earth sesquioxides, which were found to be in reasonable agreement with experimental data given in the literature.

Dielectric properties and electrical conduction in yttrium iron garnet (YIG)
TL;DR: In this article, the dielectric properties of a single crystal of yttrium iron garnet (Y3Fe5O12) were measured in the temperature range 77-725 K and in the frequency range 100 Hz-1 MHz.

Studies of polaron motion: Part II. The “small” polaron
TL;DR: In this article, the authors considered the case in which the electronic-overlap term of the total Hamiltonian is a small perturbation, and showed that the probability of off-diagonal transitions goes up exponentially with increasing temperature.
