This review shows the great impact of charge ordering upon the magnetic and transport
properties of mixed valent Co4+/Co3+ and Co3+/Co2+ cobalt oxides. The relationships …

La0. 5Sr0. 5CoO3− δ and La0. 6Sr0. 4CoO3− δ are characterized with respect to application
as cathode materials in intermediate temperature solid oxide fuel cells (IT-SOFCs). Surface …

We present a study of the thermal conductivity κ and the thermopower S of single crystals of
La 1− x Sr x Co O 3 with 0⩽ x⩽ 0.3. For all Sr concentrations, La 1− x Sr x Co O 3 has rather …

We have measured magnetic susceptibility and resistivity of Sr 1− x Y x Co O 3− δ (x= 0.1,
0.15, 0.2, 0.215, 0.225, 0.25, 0.3, and 0.4), and found that Sr 1− x Y x Co O 3− δ is a room …

This work reports on the reactivity toward carbon of a La0. 5Sr0. 5CoO3− δ perovskite
prepared by spray pyrolysis. It is shown that this perovskite presents a moderate activity for …

A family of Sr-doped perovskite compounds Ln1− xSrxCoO3− δ (Ln= La3+, Pr3+ and Nd3+;
x> 0.60), were prepared by sol–gel chemistry and reaction at 1100° C under 1atm of oxygen …

We report how the thermopower of complex transition-metal oxides is susceptible to small
changes in material parameters. In the A-site ordered perovskite oxide R2/3Cu3Ti3. 6Ru0 …

Years of intensive work on perovskite manganites has led to a detailed understanding of the
phenomena that emerge from competition between the electronic and lattice degrees of …

The effect of cation valency on the complex structures of divalent and trivalent transition
metal gallates has been examined using a combination of neutron and synchrotron X-ray …

Oxygen tracer diffusion (D⁎) and chemical diffusion (D˜) were measured in dense Sr0.
5Sm0. 5CoO3− δ (SSC) ceramics by Isotope Exchange Depth Profiling/Secondary Ion Mass …
