چکیده

The new Fe71.2B24Y4.8 glassy alloy has been prepared in amorphous ribbon form via melt spinning and splat cooling. The high degree of sample homogeneity and structural quality of the ribbon is revealed by the observation of narrow linewidths in the spectra of the field derivatives of the absorbed microwave power in ferromagnetic resonance experiments. Combination of vibrating sample magnetometry and element-specific X-ray magnetic circular dichroism experiments at the L3,2-edges of Y revealed an induced magnetic moment of 0.065 lB/atom for Y antiparallel oriented to an Fe magnetic moment of 1.83 lB/atom. 2007 Elsevier B.V.

Effect of Yttrium Addition on Glass-Forming Ability and Magnetic Properties of Fe–Co–B–Si–Nb Bulk Metallic Glass

The glass-forming ability (GFA) and the magnetic properties of the [(Fe0.5Co0.5)0.75B0.20Si0.05]96Nb4−xYx bulk metallic glasses (BMGs) have been studied. The partial replacement of Nb by Y improves the thermal stability of the glass against crystallization. The saturation mass magnetization (σs) exhibits a maximum around 2 at. % Y, and the value of σs of the alloy with 2 at. % Y is 6.5% larger ...

Enhancing glass-forming ability via frustration of nano-clustering in alloys with a high solvent content

The glass-forming ability (GFA) of alloys with a high-solvent content such as soft magnetic Fe-based and Al-based alloys is usually limited due to strong formation of the solvent-based solid solution phase. Herein, we report that the GFA of soft magnetic Fe-based alloys (with >70 at.% Fe to ensure large saturation magnetization) could be dramatically improved by doping with only 0.3 at.% Cu whi...

PROPERTIES OF ISING MAGNETIC SYSTEM FexTiS2

Analysis of frequency dependence of spin glass transition temperatures of an Ising spin glass Feo.lTiS2 shows that power law with a finite transition temperature is the most probable formula describing the experimental data. Magnetization measurement on FellaTiS2 suggests that atomically ordered FellsTiSz is an antiferrornagnet with TN = 33 K . Various transition metals are intercalated in the ...

Porphyrin grafted magnetic nanopaticles as an eco-friendly, cost-effective catalyst for green oxidation of sulfides by meta-Chloro peroxy benzoic acid

In this paper, meso-Tetraphenylporphyrin iron(III) chloride complex, Fe(TPP)Cl, supported on magnetic nanoparticles (PCMNPs) was synthesized and characterized by HRTEM, SEM, TGA, and FT-IR and VSM. The value of saturation magnetic moments of MNPs and PCMNPs are 68.5 and 60.3 emu/g, respectively. The SEM and HRTEM image were shown the uniformity and spherical-like morphology of nanoparticles wit...
