This paper presents information regarding the technology of yttrium iron garnet (YIG) film growth for magnetostatic wave (MSW) applications. The method used for film growth is liquid phase epitaxy from a molten solution of PbO/B/sub 2/O/sub 3/ into which Y/sub 2/O/sub 3/ and Fe/sub 2/O/sub 3/ have been added. An introduction to the crystalline and magnetic features found in YIG is first given. A second section deals with growth techniques and apparatus. In a third section, the melt composition, conditions of growth and homogeneity of as grown material are explored. Growth temperatures varying from 848 to 998 C have been shown to successfully produce YIG films. Possible sources of MSW loss are explored in the fourth section. It is seen that material contamination and physical irregularities may have a negative effect on Delta-H. The final section summarizes the state in which YIG film production now stands. The finding is that although usable films are producible routinely, intrinsic performance is not yet achievable on a regular basis. 53 references.
