León Yebra, Carlos ; Lucía Mulas, María Luisa ; Santamaría Sánchez-Barriga, Jacobo ; París, M. A. ; Sanz, J. ; Várez, A. | American Physical Society | 1996-07-01Lithium ionic conductivity of Li_(0.5)La_(0.5)TiO_(3) has been studied using nuclear magnetic resonance (NMR) and admittance spectroscopy (AS) techniques. Spin-lattice relaxation and electrical conductivity relaxation are well described in terms[...]texto impreso
León Yebra, Carlos ; Rivera Calzada, Alberto Carlos ; Várez, A. ; Sanz, J. ; Santamaría Sánchez-Barriga, Jacobo | American Physical Society | 2001-02-12We have analyzed the constant loss contribution to the ac conductivity in the frequency range 10 Hz–1 MHz and temperatures down to 8 K, for two Li ionic conductors, one crystalline (Li_(0.18)La_(0.61)TiO_(3)) and the other glassy (61SiO_(2) . 35[...]
