Complex oxides, such as ABO 3 perovskites, are an important class of functional materials
that exhibit a wide range of physical, chemical, and electrochemical properties, including …

Multiferroic materials, which show simultaneous ferroelectric and magnetic ordering, exhibit
unusual physical properties—and in turn promise new device applications—as a result 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 …

We have analyzed the unusual electronic structure of Sr 2 FeMoO 6 combining ab initio and
model Hamiltonian approaches. Our results indicate that there are strong enhancements of …

Monte Carlo simulation studies are performed to examine the implications of octahedral
cation (Fe, Mo) site disorder for magnetization in the double-perovskite Sr 2 FeMoO 6 …

Mixed-valence perovskite manganites (Re 1-x A x MnO 3 where Re= rare earth, A= alkaline
earth) provide a unique opportunity to study the relationships between the structure and the …

Room temperature x-ray diffraction, magnetization and neutron diffraction measurements up
to 500 K have been carried out on polycrystalline bulk double perovskites AA'FeMoO 6 (AA' …

The double-perovskite oxides Ca 2 FeMoO 6, Sr 2 FeMoO 6 and Ba 2 FeMoO 6 show
evidence of ferromagnetic metallic behaviour, with Curie temperatures of 345-426 K and …

Ceramics of A 2 FeReO 6 double perovskites have been prepared and studied for A= Ba
and Ca. Ba 2 FeReO 6 has a cubic structure (Fm3m) with a 8.0854 (1) Å whereas Ca 2 …

Magnetoresistance (MR) is the magnetic field–induced change of electrical resistance. The
MR effect not only has wide applications in hard drivers and sensors but also is a long …
