Software installation for magneto-optical to work with images of ordered domain structures
The aim is to develop software for the automation of the work of the magneto-optical device. The paper
describes the developed automated devices for the study of magneto-optical materials. Materials for
this study thin film with a magnetic anisotropy in which the two-dimensional ordered domain structures
can be formed. These materials are transparent in the infrared and visible spectral range and exhibit a
magneto-optical Faraday effect. Domain structures are of interest for the creation of controlled diffraction
gratings, baffles, switches, fiber-optic communication lines, etc. The device can change the external
influence on the sample, analyze and recognize objects (digital images), highlight the region with
the labyrinthine domain structure. External influences may be magnetic and thermal fields. Formation
of ordered two-dimensional domain structures in the material depends on the parameters of the external
field: the pulse duration, intensity, direction, offset voltage, the direction of DC offset, etc.. The device
allows you to get the equilibrium labyrinthine domain structure and register settings of external
fields. At present, the developed software is used in conjunction with a magneto-optical device for materials
research at the Department of Radio Engineering, National Research Mordovia State University.
