“…Electrical behavior of SFMO is strongly influenced by the preparation conditions of the samples: metallic behavior [6,11,21,[31][32][33][34][35][36] or insulating-like variation [3,17,21,31,34,[37][38][39][40][41][42][43] of (T) have already been reported. The existence of samples with micrometerscale grains presenting a quasi-constant resistivity has never been mentioned, in our knowledge.…”

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 report of a spectacular negative magnetoresistance effect in a specific member of this family, namely Sr2FeMoO6, has brought this class of compounds under intense scrutiny. It is now believed that the origin of magnetism in this class of compounds is based on a novel kinetically-driven mechanism. This new mechanism is also likely to be responsible for the unusually high temperature ferromagnetism in several other systems, such as dilute magnetic semiconductors, as well as in various half-metallic ferromagnetic systems, such as Heussler alloys.Comment: To appear in Current Opinion in Solid State and Material Scienc

“…This half-metallic nature of the electron states provides a nearly 100% spin polarisation in SFMO [15]. The theoretically predicted value of the magnetic moment in the double perovskite is about 4 µ B per formula unit at T = 0 K. This value is higher than those obtained experimentally [16][17][18]. This discrepancy can be explained by the formation of antisite point defects, such as [Fe Mo ], [Mo Fe ], or of oxygen vacancies (V 0 ), as well as the appearance of structural inhomogeneities, e.g.…”

Double perovskites with the structural formula A2BB′O6±δ, especially the strontium ferromolybdate Sr2FeMoO6–δ, have attracted a lot of attention due to their unique magnetic and electrical properties and a possible application in spintronic devices. However, a strict correlation between the functional characteristics of Sr2FeMoO6–δ and its synthesis technology has been lacking up to date. Thus, we have studied in the present work the crystallization kinetics of Sr2FeMoO6–δ using reagents with different pre‐history as well as the structural and magnetic properties of the obtained compounds. Differences in the crystallization kinetics as well as higher magnetic inhomogeneity of Sr2FeMoO6–δ synthesised from a mixture of MoO3, Fe2O3, SrCO3 in comparison with the compound synthesised from the SrFeO2.5 and SrMoO4–y precursors have been found and interpreted.
