Detection of the spin character of Fe(001) surface states by scanning tunneling microscopy: A theoretical proposal
Athanasios N. Chantis, Darryl L. Smith, J. Fransson +1
We consider the magnetic structure on the Fe(001) surface and theoretically study the scanning tunneling spectroscopy using a spin-polarized tip (SP-STM). We show that minority-spi…
Bias-controlled sensitivity of ferromagnet/semiconductor electrical spin detectors
S. A. Crooker, E. Garlid, A. N. Chantis +6
Using Fe/GaAs Schottky tunnel barriers as electrical spin detectors, we show that the magnitude and sign of their spin-detection sensitivities can be widely tuned with the voltage…
Strain-Induced Conduction Band Spin Splitting in GaAs from First Principles Calculations
Athanasios N. Chantis, Manuel Cardona, Niels E. Christensen +5
We use a recently developed self-consistent GW approximation to present first principles calculations of the conduction band spin splitting in GaAs under [110] strain. The spin orb…
GW method applied to localized 4f electron systems
Athanasios N. Chantis, Mark van Schilfgaarde, Takao Kotani
We apply a recently developed quasiparticle self-consistent method (QSGW) to Gd, Er, EuN, GdN, ErAs, YbN and GdAs. We show that QSGW combines advantages separately found in co…
Tunneling anisotropic magnetoresistance driven by resonant surface states: First-principles calculations of Fe(001) surface
Athanasios N. Chantis, Kirill D. Belashchenko, Evgeny Y. Tsymbal +1
Fully-relativistic first-principles calculations of the Fe(001) surface demonstrate that resonant surface (interface) states may produce sizeable tunneling anisotropic magnetoresis…
