In the present work, phase constitution and magnetic properties of LaFe11.14Co0.66Si1.2-xGax(where x = 0.1, 0.2, 0.3) alloys, were investigated.It was revealed that increase Ga content in alloy composition causes rise lattice parameter La(Fe,Si)13-type phase, which Curie temperature.However, addition leads to decrease magnetocaloric eect.
Polymer materials based on acrylic monomers are commonly used in dentistry. It is important to research the structure of dental filling towards material ageing.The study has been conducted order determine presence free volume gaps polymer materials.Brand new, samples Dipol were as a material. The was by means positron annihilation lifetime spectroscopy (PALS).As result measurements, curves describing numbers counts acts time function obtained. studies revealed existence four components τ1,...
Background. Hydrogel and silicone-hydrogel polymeric materials are widely used in ophthalmology for the manufacture of contact lenses. An important aspect is investigation structure these materials.Objectives. This study has been conducted order to compare degree disorder presence free volumes internal soft lenses Omafilcon A (hydrogel) Comfilcon (silicone-hydrogel). Differences occurrence trapping centers positrons between types investigated have demonstrated.Material Methods. Two were as...
In the present studies phase structure and magnetic ordering of magnetite nanoparticles were investigated.The powder samples obtained by co-precipitation from Fe(III) Fe(II) salts.SiO2 coating was performed using modified Stöber process.X-ray diffraction revealed presence only one Fe3O4 crystalline both for non-coated SiO2-coated samples.The Mössbauer have shown differences in shapes measured spectral lines particles subjected to process particles.The heating efficiency glycerol dispersed...
The paper presents a characterization of the phase structure by X-ray diffraction and isothermal magnetic entropy changes for amorphous Fe58Co10Zr10Mo5W2B15 alloy sample in as-quenched state.An ingot was obtained arc-melting.The ribbon melt-spinning technique.The measurements at various temperatures allowed study Curie temperature TC |∆SM |.In order to determine phase, three independent methods were used.Determination alloys is not trivial problem, as magnetization does decreases rapidly...
Studies of magnetic properties for the Gd3Zr10Fe55Co10Mo5W2B15 glassy alloy are presented.The amorphous structure melt-spun ribbon investigated was confirmed by X-ray diffractometry.The Curie temperature TC determined analyzing M (H) dependences measured at various temperatures as well from (T ) dependence low constant field.Furthermore, isothermal entropy changes | -∆SM were calculated magnetization curves to assess possibility potential application studied samples active elements in refrigerators.
