Magnetic Properties of Acicular Cobalt Ferrite Fine Particles.

Temperature dependence of magnetic properties of heat treated cobalt ferrite

This study demonstrates the effectiveness of heat treatment in optimizing the magneticproperties of cobalt ferrite, compared to other methods such as cation substitution. It also shows how the magnetic properties of the heat treated cobalt ferrite vary under differenttemperature conditions. Saturation magnetization increased more due to heat treatment than due to Zn-substitution; a cation subst...

Optimization of Magnetic Properties in Cobalt Ferrite Nanocrystals

Cobalt ferrite (CoFe2O4) possesses excellent chemical stability, good mechanical hardness and a large positive first order crystalline anisotropy constant, which made this ferrite a promising candidate for magneto-optical recording media. In addition to precise control on the composition and structure of CoFe2O4, the success of its practical application will depend on the capability of controll...

Magnetic Properties of Cadmium-cobalt Ferrite Single Crystals

Magnetic properties of single crystals of cobalt and substituted cadmium-cobalt spinel ferrites are presented under high magnetic field up to 180 kOe in the 4.2-300 K temperature range for five substitution rates. The easy direction of magnetization is [loo] whereas abrupt field transitions are observed below 150 K for the [Ill] direction. The influence of the cadmium substitution on the molecu...
