In this work, magnetic CuxNi1−x alloy nanoparticles were obtained from DCSs by a chemical reduction method. In this method magnetic CuxNi1−x alloy nanoparticles were prepared from [Cu(NH3)4][Ni(C2O4)2], [Cu(en)2][Ni(C2O4)2] and [Cu(py)4][Ni(C2O4)2] coordination complexes. Reduction of these complexes occurred in an ethanolic aqueous solution using hydrazine monohydrate. In order to characterization the synthesized compounds, we have used IR spectroscopy, EDX, SEM and XRD. The magnetic properties of the nanoalloys were measured using a Vibrating Sample Magnetometer (VSM). Magnetoimpedance (MI) measurements were performed using a Lock-in Amplifier (7265 Perkin Elmer) at a frequency of 250 kHz. These alloys demonstrate ferromagnetic behaviour which is due to the presence of nickel in the alloys. This property makes them excellent candidates for technological applications such …
