Double perovskites magnetoresistance

In the last decade, study of double perovskites has accelerated with the discovery of tunneling magnetoresistive (TMR) effects in Sr2FeMo06.i56N. Both the magnetism and transport in these oxides is strongly influenced by the cationic nature and the order/disorder of the ions at the B-site. Ferromagnetism and half-metallic properties are often... [Pg.3443]

It has been realised that the extent of cation ordering is an important issue in the synthesis of double perovskites where both thermodynamic and kinetic considerations are involved.The degree of cation order is crucial for the occurrence of unique magnetic and electrical properties. For example, magnetoresistive properties of Sr2FeMo06 vary depending on the extent of ordering of Fe and... [Pg.276]
