|Title:||Cation migration and magnetic ordering in spinel CoFe2O4 powder: Micro-Raman scattering study||Authors:||Yu, T.
|Issue Date:||23-Sep-2002||Citation:||Yu, T., Shen, Z.X., Shi, Y., Ding, J. (2002-09-23). Cation migration and magnetic ordering in spinel CoFe2O4 powder: Micro-Raman scattering study.

ScholarBank@NUS Repository. https://doi.org/10.1088/0953-8984/14/37/101||Abstract:||Micro-Raman scattering was used to characterize spinel CoFe2O4 at high temperature up to 870 K and under an external magnetic field up to 6.0 kOe. It was found that the rapid increase in the linewidth of the Raman modes was related to the inter-site cation migration starting at ∼390 K. A red-shift of the Raman peaks induced by the magnetic ordering was observed upon applying a magnetic field at room temperature. Phase analysis of CoFe2O4 powder was also carried out by means of x-ray diffraction and micro-Raman spectroscopy in this work.||Source Title:||Journal of Physics Condensed Matter||URI:||http://scholarbank.nus.edu.sg/handle/10635/114470||ISSN:||09538984||DOI:||10.1088/0953-8984/14/37/101|
