摘要：

Mn0.6Zn0.4Fe2O4 nanoparticles are fabricated by a phase transformation method in a high dc magnetic field of 60 kOe, and their structural and magnetic properties are investigated. For the 60 kOe sample, the average particle size increases and the particle size becomes uniform. Magnetic investigation displays the magnetic field enhances its saturation magnetization and decreases its magnetic loss. Results of a. c. magnetic properties reveal that the MnZn nanoferrite system is a spin-glass one. The magnetic field has effects on grain size and ion distribution, which causes high magnetization and low loss in MnZn nanoferrites. (c) 2011 American Institute of Physics. [doi: 10.1063/1.3646558]
