The B-site substituted perovskite oxides A 2 B′ B ″O 6 have in the recent decades gained
an increasing amount of interest due to their various interesting properties and possible …

We review the structural, magnetic and transport properties of double perovskites (A 2 BB'O
6) with ferromagnetism above room temperature. Ferromagnetism in these compounds is …

The perovskites and perovskite-related structures exhibit several features of technical as
well as fundamental interest. Technically useful properties include oxide-ion conduction …

The electrolyte of a solid oxide fuel cell (SOFC) is an O2−-ion conductor. The anode must
oxidize the fuel with O2− ions received from the electrolyte and it must deliver electrons of …

Magnetic oxides show a variety of extrinsic magnetotransport phenomena: grain-boundary,
tunnelling and domain-wall magnetoresistance. In view of these phenomena the role of …

The electronic structures and magnetic properties of double perovskites Sr 2 FeMoO 6, Sr 2
FeReO 6, and Sr 2 CrWO 6 have been studied by using the full-potential linear muffin-tin …

We search for general patterns that explain the low field magnetoresistance at low
temperatures in the system A (2− x) A x′ FeMoO 6. The observed linear dependence of the …

A solid oxide fuel cell (SOFC) is a promising energy conversion device with high efficiency
and low pollutant emission. The practical application of the conventional SOFCs is limited …

We survey the magnetocaloric effect in perovskite-type oxides (including doped ABO 3-type
manganese oxides, A 3 B 2 O 7-type two-layered perovskite oxides, and A 2 B'B''O 6-type …

Ordered double perovskite oxides of the general formula A2BB′ O6 have been known for
several decades to have interesting electronic and magnetic properties. However, a recent …
