We have studied the spin dynamics of confined electrons in an ultrathin CdTe/ZnTe quantum well andself-assembled quantum dots by time-resolved Kerr-rotation technique. The dependence of the spin-precessionfrequency on the magnetic field direction shows the anisotropy of the g-factor tensor, which is the opposite ofthe usual quantum wells with moderate widths. The geometrical anisotropy of the confinement also affects theinitial orientation of the electron spins created optically, as revealed clearly with the use of oblique-incidencepump pulses.
