Paper Abstract

The magnetic anisotropy constant of magnetic fluids is obtained from the angular dependence of the magnetic resonance field. The sample was frozen below room temperature under the action of a steady magnetic field of 1.45 Tesla. Magnetic anisotropy of the order of -5.4 X 104 erg/cm3 at 150 K and -5.1 X 104 erg/cm3 at 200 K was obtained for a water-based MnFe2O4 magnetic fluid sample with average particle diameter of 10.7 nm.
