摘要：

Cu-Ni alloy nanoparticles were prepared by a microwave combustion method with the molar ratios of Cu2+ to Ni2+ as 3:7, 4:6, 5:5, 6:4 and 7:3. The as-prepared samples were characterized by XRD, HR-SEM, EDX and VSM. XRD and EDX analyses suggest the formation of pure alloy powders. The average crystallite sizes were found to be in the range of 21.56-33.25 nm. HR-SEM images show the clustered/agglomerated particle-like morphology structure. VSM results reveal that for low Ni content (Cu5Ni5, Cu6Ni4 and Cu7Ni3), the system shows paramagnetic behaviors, whereas for high Ni content (Cu3Ni7 and Cu4Ni6), it becomes ferromagnetic.
