abstract = {We study the dynamics of optically induced nuclear spin
polarization in a fluorine-doped ZnSe epilayer via
time-resolved Kerr rotation. The nuclear polarization in the
vicinity of a fluorine donor is induced by interaction with
coherently precessing electron spins in a magnetic field
applied in the Voigt geometry. It is detected by
nuclei-induced changes in the electron spin coherence
signal. This all-optical technique allows us to measure the
longitudinal spin relaxation time T1 of the Se77 isotope in
a magnetic field range from 10 to 130 mT under illumination.
We combine the optical technique with radio frequency
methods to address the coherent spin dynamics of the nuclei
and measure Rabi oscillations, Ramsey fringes, and the
nuclear spin echo. The inhomogeneous spin dephasing time
T∗2 and the spin coherence time T2 of the Se77 isotope are
measured. While the T1 time is on the order of several
milliseconds, the T2 time is several hundred microseconds.
The experimentally determined condition T1≫T2 verifies the
validity of the classical model of nuclear spin cooling for
describing the optically induced nuclear spin polarization.},
