Structure and Conductivity of Pyrochlore and Fluorite Type Solid Solutions
High oxygen conductivities can be achieved in cation ordered LnxZrl_=O2_l x (Ln=Gd, Nd) solid solutions with pyrochlore (P) structure. High values of the pre-exponentlal factor °o are correlated with the degree of anion disorder in the 8b oxygen sublattice (neutron diffraction). The activation energy AH is lowered by cation ordering (F-P transition; effect of x) due to the occurence of a prefer...

Superdiffusive Conduction: AC Conductivity with Correlated Noise
We present evidence of the existence of a superdiffusive regime in systems with correlated disorder for which localization is suppressed. An expression for anomalous electrical conductivity at low frequencies is found by using a generalized Langevin equation whose memory function accounts for the interactions between the carriers. New mechanisms inducing a superdiffusive conductivity are discus...
متن کاملThe pyrochlore-type molybdate Pr1.37Ca0.63Mo2O7
Praseodymium calcium dimolybdenum hepta-oxide, Pr(1.37)Ca(0.63)Mo(2)O(7), crystallizes in the cubic pyrochlore-type structure. In the crystal structure, MoO(6) octa-hedra are linked together by common corners, forming a three-dimensional [Mo(2)O(6)] network. The Pr and Ca atoms and the remaining O atoms are located in the voids of the [Mo(2)O(6)] network. The Pr and Ca atoms are distributed sta...
متن کاملThe pyrochlore-type molybdate Pr2Mo1.73Sc0.27O7
Dipraseodymium molybdenum scandium hepta-oxide, Pr2Mo1.73Sc0.27O7, crystallizes in the cubic pyrochlore-type structure. In the crystal, (Mo,Sc)O6 octa-hedra are linked together by common corners, forming a three-dimensional [(Mo,Sc)2O6] framework. The Pr atom and another O atom atom are located in the voids of this framework. The Mo and the Sc atom are distributed statistically over the same 16...
