We present a novel and facile method enabling synthesis of iron oxide nanoparticles, which are composed mainly maghemite according to X-ray diffraction (XRD) Mössbauer spectroscopy studies. The proposed process is realized by anodic polarization in deaerated LiCl solutions containing both water ethanol. Water seems play an important role the synthesis. Morphology product was studied means transmission electron microscopy XRD. In solution almost 100% black suspension round shaped...
Superparamagnetic iron oxide nanoparticles (SPIONs) are known to be good MRI contrasts, but they have a high tendency aggregate and their biocompatibility is limited. Hyaluronic acid highly biocompatible, can provide SPION with colloidal stability, interacts specifically tumor cells through the CD44 receptor; therefore, it was used as stabilizing layer. We successfully obtained coated hyaluronic further functionalized folic construct dual-targeted system. The physicochemical properties of...
A thorough study of ${\mathrm{EuZn}}_{2}{\mathrm{P}}_{2}$ single crystals, which were grown from Sn flux, was performed using both bulk (heat capacity, ac susceptibility, dc magnetization, electrical resistivitivity, magnetoresistance) and microscopic (M\"ossbauer spectroscopy) techniques. Electrical resistance magnetic susceptibility measured also under high pressure conditions (up to 19 9.5 GPa, respectively). Further insight into electronic properties phonons is provided by ab initio...
This paper presents experimental and theoretical studies of lattice vibrations in a single-crystalline ${\mathrm{Fe}}_{3}{\mathrm{O}}_{4}(001)$ thin film. The investigations were carried out order to see how the dynamics changes at Verwey transition. Vibrational densities states (DOS) obtained from nuclear inelastic scattering (NIS) synchrotron radiation temperature range 25 296 K, while DOS calculated ab initio within density functional theory. Experimental phonon shows good agreement with...
Abstract Temperature and magnetic field dependences of electrical conductivity are systematically studied in granular films (Fe 45 Co Zr 10 ) x (Al 2 O 3 100− (28 ⩽ 64) containing crystalline metallic α-FeCo-based nanoalloy cores encapsulated an amorphous oxide shell embedded Al matrix. Formation ‘metallic core–oxide shell’ nanogranules is confirmed by transmission electron microscopy (TEM) HRTEM. The structure core governed with the difference oxidation states Fe ions investigated EXAFS,...
We used the anomalous Hall effect to study magnetic properties of MgO/Fe(t)/MgO(001) structures in which Fe thickness t ranged from 4 Å 14 Å. For iron deposited at 140 K, we obtained perpendicular magnetization room temperature below critical tc = (9 ± 1) In vicinity tc, easy axis switched an out-of-plane orientation in-plane orientation, and observed spin-reorientation transition was considered terms competition among different anisotropies. The direction attributed magnetoelastic...
The relation between nanoscale structure, local atomic order and magnetic properties of (FeCoZr)x(CaF2)100−x (29 ≤ x 73 at. %) granular films is studied as a function metal/insulator fraction ratio. thickness 1–6 μm were deposited on Al-foils glass-ceramic substrates, by ion sputtering targets different contents. Structural characterization with X-ray electron diffraction well transmission microscopy revealed that the are composed isolated nanocrystalline bcc α-FeCo(Zr) alloy insulating fcc...
Ni49.4Mn38.5Sn12.1 near single crystal was obtained by the Bridgman method. At room temperature, it consisted of a mixture parent austenite phase with cubic L21 Heusler structure (ac = 5.984 Å) and modulated, tetragonal martensite 4M (at 4.337 Å, ct 5.655 Å). Under application magnetic field, specimen undergoes field induced reverse martensitic transformation, which combined Curie transition in leads to coexistence direct inverse magnetocaloric effects. The maximum entropy change at 280 K...
