ABSTRACT:
Composites of coercive particles and superparamagnetic particles comprise an intimate admixture of said particles in a dielectric matrix. The particles are admixed in such a fashion as to provide a composite which exhibits a coercivity which behaves as if the coercive particles and the superparamagnetic particles interact. Composites exhibiting such controlled coercivity are useful in the manufacture of transformers, magnets and magnetic tapes.
