RESEARCH ON STRUCTURE AND MAGNETIC PROPERTIES OF EXPITAXIALLY GROWN MAGNETIC FILMS.
Abstract
Three major areas have been investigated. (1) An investigation of the role of imperfections in magnetic thin films has been conducted and a strong emphasis in this effort has been placed upon epitaxial properties. The results include an evaluation of voids in aged single crystals, an analysis of face-centered-cubic single crystal cobalt films and an investigation of 'ripple' as related to crystallographic properties of the epitaxial films. (2) A program to investigate the properties and origin of strip domains in various NiFe thin films was initiated. Methods for observing these domains were perfected and properties evaluated as a function of film fabrication parameters. (3) A large uniaxial anisotropy has been observed in NiFe films deposited on single crystal quartz substrates. Subsequent investigations show that its origin is a substrate-film constraint mechanism related to the planar strain system developed because of a difference in coefficients of the thermal expansion of the quartz and NiFe film.
