Pagination or Media Count:
The report discusses methods used for the characterization of magnetic bubble materials in the initial phase of the contract. These materials are magnetic garnet films epitaxially deposited on non-magnetic garnet substrates. Properties included in the garnet characterization and in this report are the following for substrates - defect identification for substrates and films - composition and lattice parameters for films only - thickness and thickness variation, defect detection and location, characteristic length and domain dimensions, saturation magnetization and magnetic field, anisotropy field, coercivity, domain wall mobility, and Neel temperature. Emphasis is on experimental detail with theory covered by appropriate references where possible.
