## Abstract We report on optical orientation experiments in undoped GaAsN epilayers and InGaAsN quantum wells (QW), showing that a strong electron spin polarisation can persist at room temperature. We demonstrate that the spin dynamics in these dilute nitride structures is governed by a spinβdepend
We studied the electron and hole spin dynamics in magnetic semiconductor quantum wells on pico-and femtosecond time scales by means of time-resolved magnetization modulation spectroscopy. Spin relaxation times of $10 ps (electrons) and $100 to 200 fs (holes) are found at room temperature for 15/15 m
