Characterization of structures and novel magnetic response of Fe87.5Si7Al5.5 alloy processed by ball milling

Comparison of the Magnetic and Absorption Properties of Flaky Super Sendust and Sendust Alloys

“…It is apparent that Ni dissolved in the a-Fe lattice. Because Ni atoms replace non-ferromagnetic atoms (Si, Al) in the Fe-Si-Al-Ni, which reduces the outermost electrons of Si atoms, occupation of the 3d shell of Fe 18 and Ni atoms can offer more Bohr magnetons. The Fe-Si-Al-Ni alloy's saturation magnetization is higher than that of Fe-Si-Al.…”

“…The Fe-Si-Al-Ni alloy's saturation magnetization is higher than that of Fe-Si-Al. According to the Williamson-Hall method, grain size and strain from the broadening of reflections can be expressed as 18 :…”

Effects of temperature and time on microstructure and microwave electromagnetic properties of Ni doped manganese dioxides

“…Theoretical analysis indicates that the order of the pros and cons of absorbing properties of absorber with different morphologies is slice-like, needle-like and sphere. 25 Hence, the morphology of products prepared in this experiment has remarkable effect on improving the electromagnetic absorbing properties of absorbent. However, the performance of absorbent properties is a complex process, which is affected by absorbent intrinsic electromagnetic properties, morphology, thickness and external field frequency, etc.…”

A new mechanism for improving electromagnetic properties based on tunable crystallographic structures of FeCoNiSixAl0.4 high entropy alloy powders

“…Second, the exchange coupling reaction of the magnetic moments between particles weakens as the surface area minishes, resulting in the increase of K 1 and decrease of m i . 42,43 Third, the increase of s and b can also reduce m i . These changing rules can be illustrated by the shape-dependent Snoek's law similarly and it's formula is showed here:…”
