Mn1-xZnxFe2O4 (x = 0, 0.1, 0.3, 0.5, 0.7) ferrite nanoparticles have been prepared by using a chemical co-precipitation method. X-ray diffraction (XRD) and vibrating sample magnetometer (VSM) measurements were utilized to study the impacts of Zn substitution on the particle size and the magnetic properties. The particles have a spinel structure and form on a nanometer scale. The Curie temperature TC, the blocking temperature TB, the coercivity H C and the particle size decrease with increasing Zn substitution.
