Circular polarization degree as a function of external magnetic field at from LEDs with (open squares) and without (open circles) . Dotted lines are guides to the eyes. The net polarization (closed squares) is plotted together with the magnetization curve measured by SQUID in arbitrary units (solid line, dashed line is a continuation as guide to the eyes).
(a) Total polarization obtained at 150 (open squares) and (closed squares). (b) Net polarization obtained at 150 (open circles) and (closed circles). Solid lines are magnetization curves measured by SQUID normalized to the net polarization in the saturation region for each temperature. Dashed lines are continuations as guides for the eyes.
Zeeman polarization calculated by Eq. (3) as a function of the ratio for temperatures of 25 (solid line), 150 (dashed line), and (dash-dotted line). The changes from 25 to and 150 to are indicated by arrows. is calculated as described in Ref. 16.
