什么也不講了,這篇文章找了好久也沒找到,為了表示誠意,全部家當(dāng)。。36G奉上求一篇文獻。 詳情: International Journal of Modern Physics B (IJMPB) Volume: 21, Issue: 5(2007) pp. 723-729 DOI: 10.1142/S0217979207036606 Title: CATION DISTRIBUTION OF MnFe2O4 NANOPARTICLES SYNTHESIZED UNDER AN INDUCED MAGNETIC FIELD Author(s): JUN WANG Department of Physics, Ningbo University, Ningbo 315211, People's Republic of China YEJUN WU Department of Physics, Ningbo University, Ningbo 315211, People's Republic of China YUEJIN ZHU Department of Physics, Ningbo University, Ningbo 315211, People's Republic of China History: Received 5 October 2005 Abstract: Nanoparticles of MnFe2O4 have been synthesized under an induced magnetic field by a hydrothermal process. A strong correlation between the cation distribution and the magnetic properties of MnFe2O4 nanoparticles has been identified. From the results of Mössbauer spectroscopy it has been found that the nanoparticles synthesized under zero magnetic fields have 21% inversion occupancy in the tetrahedral sites by Fe3+ cations, while this value decreases to 10% in the sample formed under a 0.25 T magnetic field. The results explain well the decrease in saturation magnetization from 62.2 emu/g to 52.8 emu/g for the sample formed under a magnetic field. This provides an understanding on how to control the inner structure in order to control the magnetic properties of these spinel ferrite nanoparticles. Keywords: Cation distribution; nanoparticles; magnetic properties 好心人請發(fā)到 shybluegg@hotmail.com |
