Grain boundary effect in highly ordered Sr2FeMoO6

Domenii publicaţii > Fizica + Tipuri publicaţii > Articol în revistã ştiinţificã

Autori: E. Burzo, I., Balasz, S. Constantinescu, I.G. Deac

Editorial: North Holland Elsevier, Journal of Magnetism and Magnetic Materials, 316, p.741-744, 2007.

Rezumat:

The X-ray, HRTEM, electric resistivities, magnetic and Mössbauer effect studies were performed on Sr2FeMoO6 samples. It was shown that the nonuniform composition inside the grains and that at the grain boundaries influence the magnetoresistive properties.
