Magnetoresistance in Electrodeposited Cobalt Based Alloys: Influence of Multinary Alloy Combination

Electrodeposited alloys and multilayers which unveils GMR effect, gained lot of attention in modern technology. This type of films and multilayers has great potential in technological applications, mainly in the field of Magnetoresistive sensors and MEMS devices. In past few years cobalt based magnetic alloys were vastly studied because it offers an interesting magnetic and electrical properties over other alloys. This paper deals with the investigation of preparation and magnetic behavior of electrodeposited cobalt based multinary alloys. Structural and morphological properties of the alloys were confirmed using X-Ray diffractogram and FE-SEM micrographs. Magnetic behavior of the alloys were studied using B-H loop. The magnetoresistive properties were studied using four probe technique. From the investigation it is concluded that the alloys exhibits high crystalline properties with a suitable GMR Effect for the application of Magnetoresistive Sensors.
