摘要：

It has been shown that nano-sized particles of cobalt ferrite produced by the coprecipitation method for use in magnetic fluids exhibit multiaxial anisotropy, which has not previously been reported for ferrite particles. The value of the magnetic anisotropy constant calculated from measurements of the decay of remanence is similar to that reported for bulk cobalt ferrite.
