The transmission spectra of a composite material obtained by introducing magnetite nanoparticles into a polyvinyl alcohol matrix are studied. The samples were films on the glass substrate prepared by drying an aqueous solution of polymer and a ferrofluid. A number of them were made in a constant magnetic field, which led to the formation of extended aggregates. The features of these spectra and possible causes of their appearance are discussed.

Исследованы спектры пропускания композиционного материала, полученного введением наночастиц магнетита в матрицу поливинилового спирта. Образцы представляли собой пленки на стеклянной подложке, приготовленные высушиванием водного раствора полимера и феррожидкости. Ряд из них производился в постоянном магнитном поле, что приводило к образованию протяженных агрегатов. Обсуждаются особенности этих спектров и возможные причины их появления.
