Suppression of the Magnetic Phase Transition in Manganites Close to the Metal-Insulator Crossover
F. Rivadulla, J. Rivas, J. B. Goodenough
We report the suppression of the magnetic phase transition in La1-xCaxMnO3 close to the localized-to-itinerant electronic transition, i.e. at x = 0.2 and x = 0.5. A new crossover t…
Chemical, Structural, and Transport Properties of Na1-xCoO2
F. Rivadulla, J. S. Zhou, J. B. Goodenough
We report measurement of room-temperature compressibility, thermal expansion, thermoelectric power a(T) at various pressures P < 20 kbar, basal-plane resistivity rab (T), magnetic…
Ultrasonic evidence of an uncorrelated cluster formation temperature in manganites with first-order magnetic transition at T_C
J. Mira, J. Rivas, A. Moreno-Gobbi +2
Ultrasonic attenuation and phase velocity measurements have been carried out in the ferromagnetic perovskites La_{2/3}Ca_{1/3}MnO_3 and La_{2/3}Sr_{1/3}MnO_3. Data show that the tr…
Electron scattering near an itinerant to localized electronic transition
F. Rivadulla, J. -S. Zhou, J. B. Goodenough
We report an unconventional temperature dependence of the resistivity in several strongly correlated systems approaching a localized to itinerant electronic transition from the iti…
