(a) Effective magnetic barriers for holes with spins aligned (up) and antialigned (down) to the average magnetization. (b) Modulation function for the potential barrier extracted from the curve of the magnetization vs temperature. Solid line is after Ref. 6 and dots are after Ref. 7.
MDMH: (a) charge density distribution, (b) normalized conductivities and spin polarization, (c) spin-polarized and total resistivities, and (d) spin-dependent and total mobilities. Total quantities are indicated by full lines and spin-dependent quantities by dashed lines with arrows indicating parallel (↑) or antiparallel (↓) polarization.
For , as in Fig. 2, using a logarithmic scale for the resistivity.
Same as Fig. 3 for .
