Outline of Final Research Achievements

In order to possibly apply to electromagnetic wave absorber for ultra-wide band, high saturation magnetization Fe-based spin-nano-cluster material was experimentally verified via uniquely developed chemical route. Coagulated Fe nanoparticles with magnetite nanoparticles with the average diameter of 11.1 nm and 4.6nm, respectively, showed higher blocking temperature, where the imaginary part of complex magnetic susceptibility and magnetic loss took the maximum, resulting in 223K at maximum. Thus, the hybrid material would pave the way for achieving a giant magnetic loss at around room temperature.

Academic Significance and Societal Importance of the Research Achievements

kHz帯域における従来の電磁波吸収原理は主に導体表面における表皮効果に基づいており、電磁波強度を1/100まで低減するためには数百μm~数mmの厚膜・厚板が必要となる。本研究で創製される新しいスピンナノクラスターハイブリッド材料は高効率電磁波吸収、軽量化につながる点に社会的意義がある。また、磁性材料を活用して電磁波遮蔽する手法が考案されているが、高透磁率材料で対象部品・デバイスを完全に覆わない限り完全遮蔽は出来ない。一方、本研究のハイブリッド材料における電磁波吸収は、磁気損失を主導原理としており、漏洩電磁波を熱として吸収し、完全抑制できる可能性を秘めている点に学術的意義がある。
