Current-induced magnetization switching in MgO barrier magnetic tunnel junctions with CoFeB based synthetic ferrimagnetic free layers
Jun Hayakawa, Shoji Ikeda, Katsuya Miura +12
We investigated the effect of using a synthetic ferrimagnetic (SyF) free layer in MgO-based magnetic tunnel junctions (MTJs) on current-induced magnetization switching (CIMS), part…
Magnetic Impurity States and Ferromagnetic Interaction in Diluted Magnetic Semiconductors
M. Ichimura, K. Tanikawa, S. Takahashi +2
The electronic structure of diluted magnetic semiconductors is studied, especially focusing on the hole character. The Haldane-Anderson model is extend to a magnetic impurity, and…
Domain wall displacement triggered by an AC current below threshold
Gen Tatara, Eiji Saitoh, Masahiko Ichimura +1
It is theoretically demonstrated that a displacement of a pinned domain wall, typically of order of m, can be driven by use of an ac current which is below threshold value. The…
Ferromagnetism in a Hubbard model for an atomic quantum wire: a realization of flat-band magnetism from even-membered rings
R. Arita, K. Kuroki, H. Aoki +6
We have examined a Hubbard model on a chain of squares, which was proposed by Yajima et al as a model of an atomic quantum wire As/Si(100), to show that the flat-band ferromagnetis…
