|Title:||Evolution of the microstructure and magnetic properties of Sm(Co0.6Cu0.4)(5) alloys prepared with different Sm excess content|
de Oliveira, LAS
|Abstract:||The structure of annealed Sm(Co0.6Cu0.4)(5) compounds, prepared with different Sm excess content, has been investigated by means of high resolution x-ray diffraction and scanning electron microscopy. The samples were also magnetically characterized by thermomagnetic analysis and M versus H curves at room temperature. Increasing Sm excess improves the compositional order of the 1 : 5 phase. The coercivity (H-C) and the Curie temperature (T-C) are both changed as a function of Sm excess content. The decrease in the structural defects density, resulting from the compositional order, is responsible for the observed magnetic behaviour.|
