| 中文摘要 | Cobalt ferrite CoFe(2)O(4) films were fabricated on SiO(2)/Si(1 0 0) by the sol-gel method. Films crystallized at/above 600 degrees C are stoichiometric as expected. With increase of the annealing temperature from 600 degrees C to 750 degrees C, the columnar grain size of CoFe(2)O(4) film increases from 13 nm to 50 nm, resulting in surface roughness increasing from 0.46 nm to 2.55 nm. Magnetic hysteresis loops in both in-plane and out-of-plane directions, at different annealing temperatures, indicate that the films annealed at 750 degrees C exhibit obvious perpendicular magnetic anisotropy. Simultaneously, with the annealing temperature increasing from 600 degrees C to 750 degrees C, the out of plane coercivity increases from 1 kOe to 2.4 kOe and the corresponding saturation magnetization increases from 200 emu/cm(3) to 283 emu/cm(3). In addition, all crystallized films exhibit cluster-like structured magnetic domains. (C) 2011 Elsevier B.V. All rights reserved. |
