Procesiranje, svojstva i mogućnost primene multiferoičnih materijala na bazi bizmut-ferita / Processing, properties and application of bismuth ferrite-based multiferroic materials.
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2018)
Bizmut-ferit (BiFeO3) ispoljava jedinstvena svojstva koja pre svega doprinose teorijskom shvatanju električnih i magnetnih uređenja i njihove interakcije u kristalnim oksidnim materijalima, ali bi uz prevazilažanje trenutno ...
Review of the most common relaxor ferroelectrics and their applications
(Elsevier, 2018)
Relaxor ferroelectrics were discovered almost 50 years ago among the complex oxides with perovskite structure. In recent years, this field of research has experienced a revival of interest. The dielectric relaxation ...
