Structural and magnetic properties of Co50Ni50 powder mixtures

► By using the Rietveld refinement method we found that Co50Ni50 alloy, milled for 48 h, contains two fcc solid solutions: fcc Co(Ni) and Ni(Co), beside a small amount of the undissolved Co hcp. DSC measurement as a function of milling time was carried out to confirm the existence of the hcp phase and to estimate its amount. ► By means of imageJ we found the area distribution and not just the diameter distribution. ► The coercivity is strongly related to the particles size distribution.
