Abstract
Disclosed is a method for forming a high magnetic parameter ferromagnetic material. The material has a distribution of magnetic parameters as solidified, and is separated into a first fraction having relatively high magnetic parameters and a second fraction having relatively low magnetic parameters. The method comprises applying a magnetic field to the materials, the magnetic field being high enough to magnetize the low magnetic parameter fraction, but low enough to avoid substantially magnetization of the high parameter fraction. Thereafter the fractions of material are magnetically separated.
