The effects of annealing on the magnetic properties of nanocrystalline ZnFe 2O 4 have been studied. The as-prepared sample ZnFe 2O 4 with the particle size of about 3 nm presents a relatively low blocking temperature of about 6 K as derived from the peak of the zero-field-cooled curve measured in a...
