Magnetostriction and Characterization of Bridgman Grown Rare-Earth Iron Alloys.

Abstract

We have prepared large samples of Tb sub .27 Dy sub .73 Fe sub 2 and Tb sub .2Ho sub .58 Dy sub .22 Fe sub 2 by Bridgman-like technique developed at United Technology. The samples have much larger values of saturation magnetostriction than vertically zoned materials. The materials have been characterized by metallographic and x-ray topography studies. Seeded growth resulted in a superior crystallographic orientation. Plane front growth was achieved over most of the boule.
