1Effect of Cu seed on the synthesis and characterization of FeCo alloy nano-particles by using polyol method显示文摘Fine metal particles with uniform shape, narrow size distribution and high purity are increasingly needed for specific uses in high tech industrial application. We report the direct chemical synthesis of FeCo alloy particles using the mixture of FeCl2·4H2O, Co (Ac)2·4H2O (Ac: acetate) and NaOH in ethylene glycol, and then obtained FeCo alloy particles better dispersed by adding the polyvinylpyrrolidone (PVP) and also the size could be controlled by adding copper. The prepared nano-particles were characterized using FESEM, XRD and VSM. The mean diameter of these particles was varied in the range of sub- mi- crometer to nanometer with metal-ion concentration. FeCo particles showed the typical soft magnetic properties.Uk Rae CHO Young Min LEE Shalendra KUMAR Chan Gyu LEE Bon Heun KOO 2009Science China(Technological Sciences)2009,52,1:1
