摘要
We have investigated the magnetic properties of three differently prepared samples of the spinel ZnFe2 O-4 with mu SR, neutron diffraction, Mossbauer effect and magnetization measurements. Below T-N = 10.5 K, the first sample (annealed) shows long-range antiferromagnetic order in coexistence with short-range magnetic order. The second sample (rapidly quenched) shows only short-range magnetic order. The third sample (nanostructured with an average particle size of about 9 nm) exhibits ferromagnetism below T-c approximate to 460 K combined with superparamagnetism. Below the blocking temperature of similar to 50 K the nanostructured sample exhibits a dependence on applied magnetic fields similar to that observed in spin glass systems. The roles of cation-site occupation and magnetic couplings in governing the different magnetic behaviors exhibited by the samples are discussed. (C) 2000 Published by Elsevier Science B.V.
