We analyzed the structural and magnetic properties of an array of electrodeposited cobalt nanowires grown in polycarbonate membrane with pore size 50 nm diameter and thickness β€6 ΞΌm. The currentβtime profiles were recorded during the deposition, in order to estimate and understand the growth rate and mechanism of the cobalt nanowires respectively. The formation of single and multiβdomains in the nanowires was explained by using simple domain model assumptions. The Xβray diffraction patterns show that the cobalt nanowires were grown in a mixture of fcc and hcp phases. The magnetic properties of the deposited nanowires show that the preferential magnetization orientation close to the perpendicular direction of the nanowire axis. The structural properties of the nanowires were observed by Scanning Electron Microscope (SEM). The magnetic properties were analyzed by Vibrating Sample Magnetometer (VSM) at room temperature.

## Abstract The study focuses on synthesis and characterization of transitionβmetal doped zinc oxide (Zn~1β__x__~ M~__x__~ O), which has been theoretically predicted to be ferromagnetic at room temperature. Although this system has been under experimental study for some time, the vast majority of r
