The influence of solvents on the microstructure and magnetic properties of Co2FeAl Heusler alloy nanoparticles

Size-dependent properties of single domain Fe2CoGa nanoparticles prepared by a facile template-less chemical route

“…M s of Fe 2 CoGa nanoparticles is found to decrease with a decrease in heat treatment temperature or time. The reason for the increment in the M s of HA nanoparticles at higher temperature or time has already been explained by Huynh et al , 49 Alikhanzadeh-Arani et al , 50 Yang et al 20,51 and Duan et al 21 while interpreting similar behavior in Co 2 FeAl nanoparticles. They attributed this behavior to the enhancement of the crystallinity resulting from minimizing the defects at higher heat treatment temperature or time.…”

“…While adopting template-less chemical growth, Yang et al 20 observed an increment in crystallite size of Co 2 FeAl nanoparticles upon increasing either the reaction temperature or time. Duan et al 21 also observed similar trends while processing Co 2 FeAl nanoparticles.…”

Nano-scale new Heusler compounds NiRh2Sb and CuRh2Sb: synthesis, characterization, and application as electrocatalysts

“…Some further reports claim the synthesis of Heusler nanoparticles, but the missing (111) and (200) reflections in the powder X-ray diffractograms (PXRD) indicate these compounds adopt less ordered B 2 (CsCl type) or A 2 (W type) structures instead of the ordered L 2 1 structure. 22,23…”

First-principles calculations and experimental studies on Co2FeGe Heusler alloy nanoparticles for spintronics applications

“…Here, the authors studied the influence of the pH value and composition on physical properties of Co-Fe-Al Heusler nanoparticles. Nehla et al [44] [16,[45][46][47][48]. They all have studied the structural, magnetic, and magnetocaloric properties of the NPs.…”
