Preparation and magnetic properties of MnBi alloy and MnBi /Fe hybrid magnets

open access: yesMicro & Nano Letters, 2021
MnBi alloys were prepared using arc melting with different atomic proportions between Mn and Bi and then heated at 573 K for 30 h. MnBi /Fe hybrid magnets were also prepared by modulating MnBi content.

Spin-Wave Channeling in Magnetization-Graded Nanostrips

open access: yesNanomaterials, 2022
Magnetization-graded ferromagnetic nanostrips are proposed as potential prospects to channel spin waves. Here, a controlled reduction of the saturation magnetization enables the localization of the propagating magnetic excitations in the same way that ...

Impulse Magnetization of Nd-Fe-B Sintered Magnets for Sensors

open access: yesSensors, 2016
Magnetization of large Nd-Fe-B sintered permanent magnets is still challenging. This type of permanent magnet is electrically conductive, so impulse magnetization causes a flow of eddy currents which prevent magnetization of the whole volume of the ...
