Improved Methods for Preparing Materials for Magnetic and Magneto-Optic Applications.

Abstract

A number of new techniques have been tried to improve methods for preparing various materials for magnetic and magneto-optic application. First, a high-pressure autoclave system has been developed that is capable of achieving temperatures of 1350C and pressures of 1500 atm, conditions which have not been previously obtainable. Experiments were carried out to optimize conditions for growth of rare-earth garnets from various types of fluxes. Second, a number of experiments were performed to explore the possibilities of using a vapor transport technique in synthesizing compounds containing rare earth, such as Nd, Dy, and Y with sulphur of selenium and gallium or aluminum. Third, new iron-free garnets, Na2ErMg2V3O12, have been obtained by slow cooling flux techniques using sodium vanadate as a solvent.
