spin-polarized 2DEG; (111) MOSFET; in plane magnetoresistance
要旨:
The magnetoresistance of a disordered and highly interacting
two-dimensional electron gas (2DEG) in a silicon (I 1 1) MOSFET has
been measured in the presence of a magnetic field parallel to the
surface of the 2DEG. For high electronic densities, a linear negative
magnetoconductance has been observed. The field of complete spin
saturation has been found to depend linearly on the density. From this
result, we have determined the g(*)m(*) product, which has been shown
to decrease as the density is reduced. (C) 2003 Published by Elsevier
