The electrical transport in the semiconductor two-dimensional electron gases (2DEGs) in the presence of magnetic fields have been the subject of extensive experimental and theoretical studies. Whereas the experiments generally focus on the total magnetotransport of the spin-up and spin-down electrons, the problem of how individual spin components contribute to the sum has been mostly remained untouched. Due to the Zeeman splitting of the Fermi velocities, spin-up and spin-down electrons face different resistivities against their flow. In this thesis, this problem is addressed based on electrical generation and detection of nonequilibrium spin polarization in a narrow conducting channel of 2DEG in a GaAs/AlGaAs heterostructure. It makes use ...
