Abstract Nanocrystalline Mn0.6Zn0.4Fe2O4 particles are synthesized under magnetic fields of 0 and 6T, and their structural and magnetic properties are investigated. The magnetic field enhances the grain size and the lattice strain. Magnetic measurements show that the majority of the 6T nanoparticles are superparamagnetic nearly from 40 to 300K. It is interesting that the saturation magnetization of the 6T sample is about 18% and 16% higher than that of the 0T sample at 120 and 300K, respectively.
