Abstract

Electrodeposited alloys and multilayers, which unveil the Giant Magneto-resistance effect (GMR), gained much attention in modern technology. This type of film and multilayers has great potential in technological applications, mainly in the field of Magneto-resistive sensors, MEMS devices and Environmental weather sensors. In the past few years, cobalt-based magnetic alloys were vastly studied because they offered interesting magnetic and electrical properties over other alloys. This paper was aimed at the 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. The magnetic behavior of the alloys was studied using B-H loop. The magneto-resistive properties were studied using the four-probe technique. From the investigation, it was concluded that the alloys exhibit high crystalline properties with a suitable GMR effect for the application of Magneto-resistive sensors.
