Abstract

An in-plane B parallel was applied to the [233] and [011] crystal axes. For each case, the magnetoresistance (MR) with I ∥ B and I ⊥ B was measured. A surprising anisotropy of the in-plane magnetoresistance and its temperature dependence was found. The results show that the rate of the upper spin-subband's depopulation with in-plane B critically depends on the relative orientation B and the crystal axes.
