Effect of milling conditions on structure and magnetic properties of nanocrystalline cobalt

Milling process conditions are related to magnetic properties of nanocrystalline Co material. Experiments are carried out varying plateau rotation and vial velocities. Coercivity, crystallite size and percentage of the cubic phase are analyzed using a statistical methodology based on artificial neural network. Predicted results show that the combination of low plateau rotation velocity and high vial velocity can enhance the cubic phase formation and consequently the coercivity.
