Chemical and thermomechanical compatibility between neodymium manganites and electrolytes based on ceria

Boletín de la Sociedad Española de Cerámica y Vidrio, 2008
The goal of this work was to study the thermal expansion behaviour and to establish the phase relations between NdMe0.5Mn0.5O3 (Me=Ni, Co) solid solutions as cathodes and two electrolytes based on Ce0.9Gd0.1O1.95. Doping of electrolyte with 1.0 wt% Bi2O3

Giant magnetic-field changes in radio-frequency absorption in La$_{0.67}$Sr$_{0.33}$MnO$_3$ near the Curie temperature

, 2004
The DC transport properties of and the radio-frequency (RF) wave absorption (at 2.525 MHz) in a sample of La$_{0.67}$Sr$_{0.33}$MnO$_{3}$ prepared by floating-zone method are measured. The Curie temperature, $T_{c}$, of the sample is about 374 K.

Phase Diagram of Half Doped Manganites

, 2005
An analysis of the properties of half-doped manganites is presented. We build up the phase diagram of the system combining a realistic calculation of the electronic properties and a mean field treatment of the temperature effects.

Crystalline structure and electrical properties of Dy_1-XCa_XMnO₃ solid solution

Boletín de la Sociedad Española de Cerámica y Vidrio, 2002
Solid solutions corresponding to the Dy1-xCaXMnO3 system, x=0.0 to 0.60 have been studied. The powders were prepared by solid state reaction of the corresponding oxides and carbonates. Sintered bodies were obtained by firing between 1250 and 1450ºC.

Theory of anomalous magnon softening in ferromagnetic manganites

, 1999
In metallic manganites with low Curie temperatures, a peculiar softening of the magnon spectrum close to the magnetic zone boundary has experimentally been observed.

Experimental determination of the non-extensive entropic parameter $q$

, 2005
We show how to extract the $q$ parameter from experimental data, considering an inhomogeneous magnetic system composed by many Maxwell-Boltzmann homogeneous parts, which after integration over the whole system recover the Tsallis non-extensivity ...

Glass Transition in the Polaron Dynamics of CMR Manganites

, 2002
Neutron scattering measurements on a bilayer manganite near optimal doping show that the short-range polarons correlations are completely dynamic at high T, but then freeze upon cooling to a temperature T* 310 K.
