Direct evidence for minority spin gap in the Co2MnSi Heusler alloy
Stéphane Andrieu, Amina Neggache, Thomas Hauet +6
Half Metal Magnets are of great interest in the field of spintronics because of their potential full spin-polarization at the Fermi level and low magnetization damping. The high Cu…
Engineering two-dimensional electron gases at the (001) and (101) surfaces of TiO2 anatase using light
T. C. Rödel, F. Fortuna, F. Bertran +4
We report the existence of metallic two-dimensional electron gases (2DEGs) at the (001) and (101) surfaces of bulk-insulating TiO2 anatase due to local chemical doping by oxygen va…
Surface Tomonaga-Luttinger liquid state on Bi/InSb(001)
Yoshiyuki Ohtsubo, Jun-ichiro Kishi, Kenta Hagiwara +8
A 1D metallic surface state was created on an anisotropic InSb(001) surface covered with Bi. Angle-resolved photoelectron spectroscopy (ARPES) showed a 1D Fermi contour with almost…
