On the temperature dependence of ferrofluid susceptibility

On the temperature dependence of ferrofluid susceptibility

The fulfillment of Curie– Weiss laws for a ferrofluid is critically discussed. The results of investigations of the magnetic susceptibility temperature dependences of ferrofluid and dried powder of magnetic particles are presented. The effective field parameter is computed in approximation of the ef...
