Abstract

We study the low-temperature dynamics of a shallow donor, e.g., $^{31}$ P, impurity electron spin in silicon, interacting with the bath of nuclear spins of the $^{29}$ Si isotope. For small applied magnetic fields, the electron spin relaxation is controlled by the steady state distribution of the nuclear spins. We calculate the relaxation times $T_1$ and $T_2$ as functions of the external magnetic field, and conclude that nuclear spins play an important role in the donor electron spin decoherence in Si:P at low magnetic fields.
