Аннотация:The morphology and composition of four types of two-phase alkali borosilicate glasses with magnetic atoms prepared by inductive
melting have been studied. The results of scanning electron microscopy point to uniform distribution of Na, Si, and O atoms in
these samples whilemagnetic iron atoms formball-shaped agglomerates. The magnetic properties of these agglomerates have been
confirmed by magnetic force microscopy. Atomic force microscopy had shown that in these samples two different morphological
structures, drop-like and dendrite net, are formed.The formation of dendrite-like structure is a necessary condition for production
of porous magnetic glasses.Theobtained results allowus to optimize the melting and heat treatment processes leading to production
of porous alkali borosilicate glasses withmagnetic properties.The first results for nanocompositematerials on the basis ofmagnetic
glasses containing the embedded ferroelectrics KH2PO4 demonstrate the effect of applied magnetic field on the ferroelectric phase
transition.
