|Title:||Evolution Of The Microstructure And Magnetic Properties Of Sm(co 0.6cu0.4)5 Alloys Prepared With Different Sm Excess Content|
De Oliveira L.A.S.
|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 (HC) and the Curie temperature (TC) 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. © 2009 IOP Publishing Ltd.|
