Automated system for studying magneto-optical properties of thin films of metals in situ

The method of surface magneto-optical Kerr effect (MOEK) a relatively new method of studying the magnetism of ultrathin films. This relatively simple and inexpensive method was presented for the first time by Moog and Bader in 1985 [3]. The main objectives of [1] are the creation of experimental studies of automation systems: 1) improving the efficiency and quality of research on the basis of preparation and refinement of more complete models of the objects, phenomena and processes; 2) preparation of a qualitatively new scientific results, the achievement of which is impossible without the use of automation; 3) reducing the time and reducing the complexity of research and complex tests. To conduct the study of magneto-optical properties of the in situ metal thin films, special installation has been developed, which allows measurement of magneto-optical characteristics of the films in the process of direct formation in ultrahigh vacuum. Using the developed system, a sample was provisionally deposited in situ film Fe, a thickness of about 100 Е, to the substrate Si(111) was investigated. Measurements were carried out at room temperature. The developed automated system can significantly improve the accuracy, speed and reliability when measuring magneto-optical properties of thin films in an ultrahigh vacuum.
