Witryna1 kwi 2008 · In this work, we study the systematics, at finite temperature, of the formation of local magnetic moments at a Ta impurity diluted in intermetallic Laves phases compounds XFe 2 (X = Gd, Yb). We use an extended two-coupled sublattices Hubbard Hamiltonian, to describe the Laves phases host. The d–d electronic interaction is … Witryna1 sty 1999 · We have measured the heat capacity and magnetic susceptibility of Yb 1−x Lu x B 12 single crystals in the temperature range from 4 to 300 K. For x⩽1/2, formation of an energy gap is manifested by a strong decrease in the magnetic susceptibility below 100 K.The heat capacity exhibits a Schottky anomaly with an activation energy of …

Witryna1 paź 2024 · Strained cuboid Yb-doped NaMgF 3 nanoparticles were synthesised via a hydrothermal synthesis technique. The morphologies and crystal phases of the nanoparticles were the same for two different Yb concentrations (0.1% and 1%). Prior to X-ray exposure, photoluminescence was observed from O 2− impurities, Yb 3+, and … Witryna19 gru 2024 · The NCA 177 Lu and pure 175 Yb were produced with radionuclidic purity of 99.99 and 99.97% respectively by irradiation of enriched 176 Yb target in thermal neutron flux of 5 × 10 13 n/cm 2 s for 14 days. 177 Lu-DOTMP and 175 Yb-DOTMP were obtained with high radiochemical purities (> 95%) under optimized reaction conditions.

The quality or condition … WitrynaThe concentration of Yb 3+ ions increases monotonically with the ytterbium content, while a significant fraction of ytterbium ions remains in a nonmagnetic Yb 2+ state. This is explained within the electronic band-structure model, assuming the ytterbium-derived donor states form an impurity band in the vicinity of the valence-band top.

Witryna16 wrz 2013 · The excited-state structure of impurity-trapped excitons are measured in a multisite system. We use a two-color (UV-IR) pulsed photoluminescence enhancement technique, which probes the interlevel transitions and dynamics of impurity-trapped excitons in doped insulating phosphor materials. The technique is applied to …
