Magnetic properties of porous spheres BiFeO 3 have been studied at temperatures ranging from 2 to 300 K. A transition to cluster spin glass state has been detected in the region of about 100 K. The presence of the transition is confirmed by nonlinear variation of coercive force and the appearance of exchange displacement of magnetic hysteresis loops at temperature below 100 K. Temperature dependence of magnetization for zero-field cooled regime exhibit a maximum at some temperature Tm. The function Tm(H) (H is magneic field) changes in accordance with Almeida-Thouless line. The performed measurements of the frequency dependence of AC susceptibility confirm the behavior of spin glass with spin freezing temperature T f = 116 K. The critical index zν = 2.5 agrees well with the mean-field theory zν = 2.0.

Attracted materials nanostructures consist of bismuth ferrite strong attention to being a candidate optimistic in many applications due to perovskite structure as aspect of relevance to electronic structure and chemical bonding. This review article focuses on recent developments regarding the synthesis, characterization, and applications of BiFeO3 nanostructures.The synthesis of bismuth ferrite with different morphologies phases parameters as exhibits multi-ferroic properties of both ferroelectric ordering and antiferromagnetic ordering which is useful for applications in memory, spintronic photovoltaics and magneto-electric sensor devices. Based on account of advanced characteristics like electrical resistance, the multiferroic BiFeO3 nanomaterials are emerged to be a tough challenger in the several physiochemical research area in comparison to the other inorganic perovskites nanostructures.

“…Среди различных методов синтеза ультразвуковой спрей-пиролиз (USP) является простым и универсальным подходом, позволяющим управлять процессом самосборки полых сфер из растворов. Изменяя скорость удаления растворителя (за счет варьирования температуры сушки капель аэрозоля) и скорость диффузии растворенных компонент (за счет образования металлоорганических комплексов), получают сферы различной морфологии [25,26,27].…”

Nanostructured hollow spheres of Co3O4 were synthesized by ultrasonic spray pyrolysis. Nanocrystals forming the structure of spheres differ in size and packing density, depending on the synthesis conditions. The samples were certified by X-ray diffraction, scanning electron microscopy, low-temperature nitrogen sorption, vacuum pycnometry, Raman and XPS spectroscopy. The field and temperature dependences of the magnetization showed that the size and packing density of nanocrystals determine the magnetic characteristics and the Néel temperature of hollow Co3O4 spheres.
