Abstract :
Vacuum sintering has been found to result in large decrease in the electrical resistivity of cobalt ferrite samples which led to the enhancement of the thermoelectric properties compared to samples prepared by other methods. Magnetization of the sample was found to be affected by a (Co1-xFex)O phase developed due to the reducing nature of the vacuum chamber in which the samples were sintered. The Curie temperature obtained for the samples is similar.
