Simultaneous study of magnetic and electrocatalytic properties cobaltites under extreme conditions expands the understanding physical chemical processes proceeding in them with possibility their further practical application. Therefore, La0.6Sr0.4CoO3 (LSCO) nanopowders were synthesized at different annealing temperatures tann = 850–900 °C, multifunctional studied comprehensively. As increases, rhombohedral perovskite structure LSCO becomes more single-phase, whereas average particle size...
Manganites are multifunctional materials which widely used in both technology and devices. In this article, new prospects of their use as nanoparticles for various types applications demonstrated. For that, the ferromagnetic nanopowder La0.6Sr0.4MnO3 has been synthesized by sol-gel method with a subsequent annealing at 700-900 °C. The crystal structure, phase composition morphology well magnetic, magnetothermal electrocatalytic properties have studied comprehensively. critical sizes...
Prospects for the use of manganites in various areas modern technologies require comprehensive studies their physical and chemical properties. La0.9Mn1.1O3 (LMO) ceramics have been synthesized at an annealing temperature tann 1150 °C with further post-annealing 1250, 1350, 1450 °C. As increases, structure symmetry changes, both crystallite size defects increase. The post-annealing, on one hand, leads to a dramatic reduction magnetocaloric effect (MCE) |-ΔSmaxM| from 3.50 0.75 J (kg K)-1 2 T...
For many medical applications related to diagnosis and treatment of cancer disease, hyperthermia plays an increasingly important role as a local heating method, where precise control temperature parameters the working material is strongly required. Obtaining smart with "self-controlled" in desirable range relevant task. this purpose, nanopowder manganite perovskite super-stoichiometric manganese has been synthesized, which consists soft spherical-like ferromagnetic nanoparticles average size...
Abstract In this work, a novel multiferroic‐like nanocomposite is designed and obtained using the high‐pressure torsion (HPT) method. The crystal structure, phase composition, morphology, ferromagnetic (FM), ferroelectric (FE) properties of initial powders ferroelectric/ferromagnetic nanocomposites are studied comprehensively. their composite show perovskite spinel crystalline phases for FE FM fractions, respectively. After HPT, particle sizes decreased significantly. It shown that consists...
A magnetoactive elastomer (MAE) consisting of single-domain La0.6Ag0.2Mn1.2O3 nanoparticles with a Curie temperature close to room (TC = 308 K) in silicone matrix has been prepared and comprehensively studied. It found that MAE particles are magnetized superparamagnetically low coercivity below 10 Oe at above. The influence magnetic anisotropy on the appearance torque is justified. coupling between magnetization magnetoelasticity also established. mechanisms magnetoelasticity, including...
The properties of nanoparticles are determined by their size and structure. When exposed to external pressure P, structural can change. improvement or degradation the samples depending on time is particularly interesting. knowledge influence structural-size effect, aging time, behavior compounds essential for fundamental applied purposes.Therefore, first attempts have been made shed light how functional Mn-containing perovskites change them. different sizes, from 20 70 nm, obtained. After 3...
Structure and its defects, magnetic resonance magneto-transport properties of La0.6–xEuxSr0.3Mn1.1O3–δ magnetoresistive ceramics were investigated by x-ray diffraction, thermogravimetric, resistance, magnetic, 55Mn NMR magnetoresistance methods. It was found that isovalent substitution lanthanum europium A-cation a smaller ionic radius increases the structural imperfection leads to symmetry change from rhombohedrally distorted perovskite structure R3¯c pseudocubic type. shown real contains...
