Electron-spin dynamics in semiconductorbased heterostructures has been investigated in oblique magnetic fields. Spins are generated optically by a circularly polarized light, and the dynamics of spins in dependence of the orientation (h) of the magnetic field are studied. The electron-spin precession frequency, polarization amplitude, and decay rate as a function of h are obtained and the reasons for their dependences are discussed. From the measured data, the values of the longitudinal and transverse components of the electron g-factor are estimated and are found to be in good agreement with those obtained in ...

The possible mechanisms responsible for the observed effects are also discussed.
