DoD Project: 7371
DoD Task: 737103
Identifier: AD0288288
Abstract:
An experimental apparatus was built which employs the magneto-optical Kerr ef ect for visual observation and photographic recording of magnetic domain patterns. The main objective of this work was to familiarize the investigators with the problems of the Kerr technique and thus provide the basis for designing a more sophisticated apparatus. This report dicusses the Kerr effect and its application to the study of magnetic domains and analyzes some of the optical problems incurred in this application. It describes the experimental set-up and presents pictures of domain structures observed on a thin film of Permalloy.
