Improved Magneto-Optical Indicator Films By Combustion Chemical Vapor Deposition

In response to the need for improved magneto-optical indicator films for real-time characterization of magnetic domain structures, MicroCoating Technologies (MCT) proposes to enable the fabrication of epitaxial, high performance YIG magneto-optical thin films by combustion chemical vapor deposition (CCVD) process at low cost. With the rapid pace of optical telecommunications and optical information process and storage, there is an increasing need for magnetic films, and magnetic film based devices and systems. Therefore, a reliable and simple imaging technique for real-time characterization of magnetic domain structures is becoming more and more important. Rapid response to customer requirements and further cost reductions are essential to respond to the future marketplace. CCVD technique offers an attractive alternative to enable synthesis of these magneto-optical thin film materials for real-time imaging applications. The success in this proposed project will enable the U.S. to maintain leadership in the global competition in this area. The end of Phase 1 objectives are a film thickness of larger than 1 mm, a surface roughness of less than 5 nm, and a Faraday rotation of larger than 100,000o/cm.
