Unusual band evolution and persistence of topological surface states in high-T_C magnetic topological insulator
K. Hori, S. Souma, C. -W. Chuang +12
Understanding the mechanism of ferromagnetism in ferromagnetic topological insulators (TIs) is a key to realize exotic time-reversal-symmetry-broken quantum phases. However, electr…
Magnetic and transport properties of Sb2Te3 doped with high concentration of Cr
Sachin Gupta, Shun Kanai, Fumihiro Matsukura +1
We report on molecular beam epitaxy and properties of a magnetic topological insulator, Cr doped Sb2Te3. The composition analysis reveals that Cr replaces Sb site, and x-ray diffra…
Magnetization dynamics and its scattering mechanism in thin CoFeB films with interfacial anisotropy
Atsushi Okada, Shikun He, Bo Gu +9
Studies of magnetization dynamics have incessantly facilitated the discovery of fundamentally novel physical phenomena, making steady headway in the development of magnetic and spi…
Fermi level position, Coulomb gap, and Dresselhaus splitting in (Ga,Mn)As
S. Souma, L. Chen, R. Oszwaldowski +5
Carrier-induced nature of ferromagnetism in a ferromagnetic semiconductor, (Ga,Mn)As, offers a great opportunity to observe novel spin-related phenomena as well as to demonstrate n…
Electric-field modulation of exchange stiffness in MgO/CoFeB with perpendicular anisotropy
T. Dohi, S. Kanai, A. Okada +2
We observe magnetic domain structures of MgO/CoFeB with a perpendicular magnetic easy axis under an electric field. The domain structure shows a maze pattern with electric-field de…
CoFeB Thickness Dependence of Thermal Stability Factor in CoFeB/MgO Perpendicular Magnetic Tunnel Junctions
H. Sato, M. Yamanouchi, K. Miura +4
Thermal stability factor (delta) of recording layer was studied in perpendicular anisotropy CoFeB/MgO magnetic tunnel junctions (p-MTJs) with various CoFeB recording layer thicknes…
