As the matrices polyvinyl alcohol and epoxy resin were used, however, the results obtained may be applicable to other media, for example, biological. The data of this work can be useful both for physical investigations of magnetic nanomaterials and for more practical studies, for instance, aimed at solving some environmental problems.</p></abstract><trans-abstract xml:lang="ru"><p>В статье были проанализированы структуры, образующиеся при воздействии магнитного поля на наночастицы магнетита, внедренные из феррожидкостей в прозрачные матрицы.
