Anelastic spectroscopy study of the metal-insulator transition of Nd(1-x)EuxNiO3
F. Cordero, F. Trequattrini, V. B. Barbeta +2
Measurements are presented of the complex dynamic Young's modulus of NdNiO3 and Nd0.65Eu0.35NiO3 through the Metal-Insulator Transition (MIT). On cooling, the modulus presents a na…
Metal-insulator transition in Nd1-xEuxNiO3 probed by specific heat and anelastic measurements
V. B. Barbeta, R. F. Jardim, M. S. Torikachvili +4
Oxides RNiO3 (R = rare-earth, R # La) exhibit a metal-insulator (MI) transition at a temperature TMI and an antiferromagnetic (AF) transition at TN. Specific heat (CP) and anelasti…
Magnetic properties of Fe3O4 nanoparticles coated with oleic and dodecanoic acids
V. B. Barbeta, R. F. Jardim, P. K. Kiyohara +2
Magnetic nanoparticles (NP) of magnetite (Fe3O4) coated with oleic acid (OA) and dodecanoic acid (DA) were synthesized and investigated through Transmission Electron Microscopy (TE…
Magnetothermopower in Nd1-xEuxNiO3 compounds
V. B. Barbeta, R. F. Jardim, M. T. Escote +1
We have measured magnetization M(T,H), electrical resistivity ro(T,H), thermal conductivity k(T,H), and thermopower S(T,H) of polycrystalline samples of Nd1-xEuxNiO3; 0 <= x <= 0.3…
Metal-insulator transition in NdEuNiO compounds
M. T. Escote, V. B. Barbeta, R. F. Jardim +1
Polycrystalline NdEuNiO () compounds were synthesized in order to investigate the character of the metal-insulator (MI) phase transition in thi…
