Study of the Fe-Co Alloy Ultrafine Powders Produced by Sonochemistry

Iron-Cobalt alloy ultrafine powders have been prouced by sonochemistry,the particle size and the components of samples have been analyzed by TEM,XRD and XPS,at the same time,the magnitic parameters are measured by a vibrating sample magnetometer. We confirm that sample is the Fe-Co alloy ultrafine powders that have been reported by experiments,and this may open a new way to synthesize other iron-based alloy powders using sonochemistry method.
