摘要：

The Copper doped nickel ferrites were integrated by the co-precipitation method at 900 degrees C in this study. XRD patterns reveal the synthesized material are in single phase, face-centered Cubic (FCC) spinel structure and got good crystallinity with 10-20 nm in size. FT-IR confirmed high (426-456 cm(-1)), low (346-387 cm(-1)) frequency integration of tetrahedral and octahedral voids and confirmed inverse spinel structure. The ferrimagnetic properties of all synthesized materials at different concentrations were declared by the VSM. EPR analysis confirmed that existence of paramagnetic centers proves the evidence of free radicals in the ferrite materials.
