description: The object under the study is optoelectronic devices containing ferrofluid as an active element, the optical parameters of which are controlled by the application of an external magnetic field. The purpose of the work is to analyze the principles of creating optoelectronic devices using ferrofluid as a controlled element and to prepare a review of the current state of research in the field of using ferrofluids in optoelectronic devices, as well as to compare various devices of this type. In the bachelors work, ferrofluids (magnetic fluids) are considered - materials whose physical characteristics can be controlled by applying a magnetic field. The paper considers the mechanisms of changing the optical parameters of ferrofluids under the influence of an external magnetic field and shows how it can be used to create an optoelectronic device. Specific examples of such devices are given and the principles of their operation are considered. It is shown that ferrofluid can be used in controlled filters, magnetic field sensors, spectrum analyzers and other devices. In the course of the study, open educational resources and information search and analysis programs were used. The possibility of automating a number of optical experiments is shown; the application of the Multisim program for modeling in problems related to the subject of the work is discussed.
