Abstract |
大きな磁化を持つ強磁性状態を電気磁気効果を用いて制御する手法を2つの観点から研究した。まず, 交換増大した金属のフェルミエネルギーを電場により変化させてストーナーの強磁性発現条件の境界で磁性制御を行う。この手法にはPdのナノ粒子と超薄膜を用いた。次に, 相互作用の強い強磁性ナノ粒子集合体において, ナノ粒子の磁気異方性を電場で変化させ, 相互作用と磁気異方性の比を制御して集合体の磁性制御を目指す。この手法には純鉄のナノ粒子集合体を用いた。これより, スピントロニクス分野における磁気応用技術開拓の基礎となるナノ粒子・超薄膜および強磁性ナノ粒子集合体の磁気秩序制御手法に関する多くの知見を得た。
Control method of ferromagnetic state with large spontaneous magnetization using the magnetoelectric effect is studied from two points of view. First, the magnetic control is performed by changing the Fermi energy of exchange-enhanced metal using electric field at a boundary of Stoner criterion for appearance of ferromagnetism. In this method, nanoparticle and ultra thin film of Pd are used. Next, the ferromagnetic nanoparticle assembly with strong magnetic interaction is magnetically controlled through the change in the ratio of magnetic interaction and magnetic anisotropy by changing the magnetic anisotropy energy of nanoparticle by electric field. In this method, assembly of pure Fe nanoparticles is used. Based on this, much knowledge about method for controlling magnetic ordering of nanoparticle/ultra thin film and ferromagnetic nanoparticle assembly, which becomes a basis of the development of magnetic application technology in the field of spintronics, was obtained.
