Nanocrystalline Fe-Al2O3 soft-magnetic composite powders were synthesized by a conventional combustion method followed by a H2 reduction process. In this paper, we analyzed the effect of the types… (More)
The frequency for wireless power chargers is in the range of 100–205 kHz when using MnZn ferrite and NiZn ferrite. Compared to ferromagnetic metals, these ferrites have higher resistivity, which… (More)
Currently, MnZn ferrite and NiZn ferrite have been widely used as magnetic shielding materials for WPC operating in the frequency range of 100∼205 kHz.
Composite sheets including Fe–Co magnetic hollow fibers are applicable to near-field electromagnetic wave absorption sheets operating in excess of 1 GHz. To understand the frequency-dependent… (More)
FeCo hollow fibers can possess high anisotropy field due to their high aspect ratio.
Macroscopically core-shell structured Fe@FeSiAl oxide nanoparticles and their composite sheets were manufactured through a series of simple procedures such as solution combustion synthesis, hydrogen… (More)
Soft magnetic composites using metallic magnetic powders have extensively been investigated for the application to mobile electromagnetic devices, particularly motor cores. These metal powders are… (More)
