Nanocrystalline Fe and Fe-riched Fe-Ni through electrodeposition

There is a constant need for new softer magnetic materials, especially with high saturation moments. A number of studies have shown that by decreasing the average crystal size of a material below 20 nm, it is possible to reduce its magnetic losses. This was clearly demonstrated in nanostructured magnetic alloys based on the thermal crystallization of amorphous ribbons. However, this demonstration has been very difficult for other nanostructured materials mainly because most of them are based on powder processing. This study presents the synthesis and properties of nanostructured magnetic materials produced by pulsed electrodeposition. Surprisingly compared to other synthesis techniques, electrodeposition has received little attention for producing large quantities of fully dense nanostructured materials. in this work we describe some of the electrodeposition parameters leading to the production of nanostructured Fe and Fe-riched Fe-Ni alloys. Some magnetic properties obtained using a vibrating sample magnetometer are also presented (C) 1999 Acta Metallurgica Inc.
