Spinel ferrite Cu1-xZnxFe2O4 nanofibers over a compositional range 0 < x < 1were prepared by electrospinning combined with sol-gel method. The influence ofZn2+ ions substitution on morphology, structure, and magnetic properties ofcopper ferrite has been investigated. The results show that surface of CuFe2O4nanofibers consists of small open porosity, while surface of doped nanofibersreveals smooth and densified nature. With increasing Zn substitution,saturation magnetization initially increases and then decreases with a maximumvalue of 58.4 emu/g at x = 0.4, coercivity and square ratio all decrease. Theinfluence of substitution on magnetic properties is related with the cationdistraction and exchange interactions between spinel lattices.
