Quadratic Fermi Node in a 3D Strongly Correlated Semimetal
Takeshi Kondo, M. Nakayama, R. Chen +18
Strong spin-orbit coupling fosters exotic electronic states such as topological insulators and superconductors, but the combination of strong spin-orbit and strong electron-electro…
Tunneling anisotropic magnetoresistance of NiFe/IrMn/MgO/Pt stack: An antiferromagnet based spin-valve
B. G. Park, J. Wunderlich, X. Marti +9
Spin-valve is a microelectronic device in which high and low resistance states are realized by utilizing both charge and spin of carriers. Spin-valve structures used in modern hard…
MgO barrier-perpendicular magnetic tunnel junctions with CoFe/Pd multilayers and ferromagnetic insertion layers
K. Mizunuma, S. Ikeda, J. H. Park +7
The authors studied an effect of ferromagnetic (Co20Fe60B20 or Fe) layer insertion on tunnel magnetoresistance (TMR) properties of MgO-barrier magnetic tunnel junctions (MTJs) with…
Superconductivity in undoped T'-RE2CuO4 with Tc over 30 K
O. Matsumoto, A. Utsuki, A. Tsukada +3
In this article, we report the superconductivity in T'-RE2CuO4 (RE = Pr, Nd, Sm, Eu, and Gd), which have been for a long time believed as a Mott insulator. Our discovery was achiev…
Charge transfer gap for T'-RE2CuO4 and T-La2CuO4 as estimated from Madelung potential calculations
A. Tsukada, H. Shibata, M. Noda +2
T'-RE2CuO4 (RE: rare-earth element), after appropriate "reduction", has fairly high conductivity and also exhibits clear Fermi edge in photoemission spectroscopy. To clarify the or…
Doping of Ce in T-La2CuO4: Rigorous test for electron-hole symmetry for high-Tc superconductivity
A. Tsukada, H. Yamamoto, M. Naito
We report that Ce doping was achieved in La2CuO4 with the K2NiF4 (T) structure for the first time by molecular beam epitaxy. A synthesis temperature of as low as ~ 630C and an appr…
