Coexistence of ferromagnetic and glassy behavior in semiconducting LaNi 0.2Co 0.8O 3
(2002)Systematic dc and ac magnetic susceptibility studies have been performed on single-phase LaNi 0.2Co 0.8O 3 powder samples. Evidence of hysteresis loops supports the existence of ferromagnetic correlations that lead to a ...

Crystal/glass phase change in KSb5S8 studied through thermal analysis techniques
(2004)The reversible crystal-glass and glass-crystal transitions discovered in KSb5S8 were studied in detail with nonisothermal scanning calorimetry techniques. When cooled, molten KSb5S8 becomes a metastable glass, which can ...

Electrical, structural, and optical properties of sulfurized Sn-doped In2O3 nanowires
(2015)Sn-doped In2O3 nanowires have been grown on Si via the vapor-liquid-solid mechanism at 800 °C and then exposed to H2S between 300 to 600 °C. We observe the existence of cubic bixbyite In2O3 and hexagonal SnS2 after processing ...

Enhanced photon harvesting in silicon multicrystalline solar cells by new lanthanide complexes as light concentrators
(2011)Four europium complexes with enhanced luminescent properties have been synthesized. Thin transparent films of the complexes were prepared on glass panes and then were examined as efficient luminescent solar concentrators ...

Infrared spectroscopic study of vacuum evaporated amorphous thin films of MoO3-SiO
(1990)A series of amorphous MoO3-SiO thin films of varying compositions were investigated by infrared spectroscopy. In some cases, a shift in band frequency was observed. Some new peaks appeared when SiO was mixed in MoO3. These ...

Investigation of infrared absorption spectra of copper phosphate glasses containing some rare earth oxides
(1990)The spectra of copper-lutetium-phosphate and copper-erbium-phosphate glasses have been studied within the spectral range 4000 to 400 cm- by Fourier transform infrared spectroscopy. Incorporation of a small amount of lutetium ...

Local structure and influence of bonding on the phase-change behavior of the chalcogenide compounds K1-xRbxSb5S8
(2007)KSb5S8 and its solid solution analogs with Rb and Tl were found to exhibit a reversible and tunable glass→crystal→glass phase transition. Selected members of this series were analyzed by differential scanning calorimetry ...

Magnetoresistance in LaNi1-xCoxO3 (0.3≤x≤0.6)
(2010)We report on a detailed study of the electrical resistivity and the magnetoresistance of the metallic members of the LaNi1-xCoxO3 series with 0.3≤x≤0.6. The low-temperature resistivity of the compounds with 0.3≤x≤0.5 ...

Structural characterization of glassy and rubbery model anionic amphiphilic polymer conetworks
(2008)The structure of two series of model amphiphilic polymer conetworks based on the hydrophilic anionic methacrylic acid was characterized by atomic force microscopy (AFM) and small-angle neutron scattering (SANS). In the ...
