Abstract: FeCo/Cu core shell structure with FeCo as a core and copper as the shell has been successfully synthesized by displacement reaction. The morphology, grain size, lattice strain, and magnetic properties of all the samples were examined by using transmission electron microscopy (TEM), X-ray diffraction (XRD), and vibrating sample magnetometer (VSM). The effect of magnetic properties of the FeCo/Cu core shell particles was investigated with respect to the annealing temperatures. A remarkable increase in coercivity (Hc) of heat treated samples with and without magnetic field from 389.84G to 397.59G was recorded. The blocking temperatures (Tb) and squareness (Mr/Ms) of the sample gradually increased due to the influence of temperature and magnetic field.
