- Abstract
In this contribution we present the first results devoted to studies of structure, morphology and magnetic properties of magnetic alkali-borosilicate glasses prepared by induction melting. This procedure permits to fabricate a large amount of two-phase glasses with magnetic properties due to self-assembled magnetite (Fe 3 O 4 ) nanoparticles and with branched dendrite-like structure of channels formed by a chemical unstable phase. After withdrawal of this phase we have obtained the porous matrices with two different average pore diameters: ∼6 nm and ∼60 nm. The empty pore spaces in these matrices were filled by ferroelectrics KH 2 PO 4 from water solution. It is shown that application of external magnetic fields above B=1 T results in a linear growth of the ferroelectric phase transition temperature T C on 6 K at B=10 T due to magnetostrictive properties of porous matrices.
