title = "Synthesis, magnetic and electromagnetic absorption properties of amorphous core-shell Fe-B@SiO2 submicrospheres",
abstract = "Amorphous core-shell Fe-B@SiO2 submicrospheres with the SiO2 shell layer of about 18 nm were fabricated via a two-step process. Fe-B submicrospheres were first obtained, and core-shell Fe-B@SiO2 submicrospheres were subsequently fabricated using TEOs as a Si source through a modified St{\"o}ber method. The measurements of the magnetic properties demonstrated that the amorphous core-shell Fe-B@SiO2 submicrospheres exhibit ferromagnetic behavior at room temperature. The maximum reflection loss reaches -24.8 dB at 11.76 GHz for the absorber with thickness of 2.2 mm. The absorption bandwidth with the reflection loss below -10 dB is up to 14.76 GHz for the absorber with a thickness of 1.5-6 mm and the absorption bandwidth with the reflection loss below -20 dB is up to 6.6 GHz for the absorber with a thickness of 1.8-3.1 mm. Our results demonstrates that the amorphous core-shell Fe-B@SiO2 submicrospheres obtained in this work are attractive candidate materials for the magnetic and EM wave absorption applications.",
