description: The subject of the graduate qualification work is âferromagnetic liquidsâ. In the course of the work, two optical methods for studying ferromagnetic liquids were developed: the method of laser correlation spectroscopy and the method of detecting transmission spectra. Using the method of laser correlation spectroscopy, the processes of aggregation and decomposition of particles in ferromagnetic liquids that occur in an external magnetic field were studied. The dependence of the average size of aggregates on the magnitude of the applied field is found. It has been established that large clusters are more susceptible to aggregation and decomposition than small formations and single particles. The transmission spectrum of the sample and the intensity of the transmission depending on the applied magnetic field were determined by the method of detection of the transmission spectra. It is shown that the transmission intensity decreases in proportion to the applied field for each wavelength in the spectrum. The terminological features of the subject area are taken into account and software tools are used to solve problems. Specialized software and mathematical software Microsoft Excel and OriginPro were used. The results obtained are new and can be applied in the development of magnetically controlled optical devices.
