Fabrication of Soft Magnetic Fe-based Nanoalloy
The Fe-Ni-Sb-B amorphous alloy has been prepared by a solid-solid chemical reaction of ferric trichloride, nickel chloride, antimony chloride and potassium borohydride powders at room temperature. The inductive couple plasma study indicates that the resultant is composed of Fe 5.38 %, Ni 56.19 %, Sb 29.02 % and B 0.44 %. The XRD and thermal analysis show that the alloy is a non-strict sense amo...
متن کاملFeCo-BASED SOFT MAGNETIC NANOCRYSTALLINE ALLOYS
The influence of microstructure on the magnetic properties is studied in series of of FeCoNbB, FeCoZrB and FeCoMoBCu amorphous and nanocrystalline alloys with different amount of crystalline phase.V arious thermomagnetic treatments have been used in order to tailor the soft magnetic characteristics of these alloys for potential applications. We report on a beneficial effect of both longitudinal...

متن کاملMAGNETIC STATES INSTABILITY OF Pt-Fe ALLOYS
Neutron-diffraction measurements have been used to 'determine the temperature and composition dependences of the ordered single crystals of Pt-Fe alloys containing 32, 30.5 and 28 at% of iron. A qualitative model for the complex antiferromagnetic ordering in the system based on the experimental data and band structure calculations has been proposed. The ordered Pt-Fe alloys with more than 36 at...
متن کاملMagnetic domains in magnetostrictive Fe–Ga alloys
Lorentz microscopy was applied to the observation of magnetic domains in iron-gallium (Fe–Ga) alloys. Results did not show any link between the magnetic domains and the magnetostriction enhancement by Ga addition, but did reveal that the drastic decrease in magnetostriction for Fe–31.2 at. % Ga was due to the presence of large scale precipitates. Magnetic domain features did not change in the a...
