Spin-Polarized Tunneling as a probe of (Ga,Mn)As electronic properties
M. Elsen, H. Jaffres, R. Mattana +3
We present magnetic and tunnel transport properties of (Ga,Mn)As/(In,Ga)As/(Ga,Mn)As structure before and after adequate annealing procedure. The conjugate increase of magnetizatio…
Co-doped (La,Sr)TiO3-d: a high-Curie temperature diluted magnetic system with large spin-polarization
G. Herranz, R. Ranchal, M. Bibes +12
We report on tunneling magnetoresistance (TMR) experiments that demonstrate the existence of a significant spin polarization in Co-doped (La,Sr)TiO3-d (Co-LSTO), a ferromagnetic di…
Electrical detection of spin accumulation in a p-type GaAs quantum well
R. Mattana, J. -M. George, H. Jaffres +5
We report on experiments in which a spin-polarized current is injected from a ferromagnetic electrode into a quantum well through an AlAs barrier. The resulting spi…
Field dependence of magnetization reversal by spin transfer
J. Grollier, V. Cros, H. Jaffres +6
We analyse the effect of the applied field (Happl) on the current-driven magnetization reversal in pillar-shaped Co/Cu/Co trilayers, where we observe two different types of transit…
