Abstract

Magnetic properties related to nano-structure have been investigated for sol-gel grown Co-ferrite thin films on the substrates of glass and SiO 2(100). The magnetic properties depended on the annealing temperature and the coercivity of 7.7 kOe was obtained at 923 K on the SiO2(100) substrate. The microstructure transformed into columnar from granular at the annealing temperature of 923 K.
