Spin effects at above-threshold ionization of hydrogen-like highly-charged ions in a laser field are investigated. The spin-resolved ionization rates are calculated employing the relativistic standard strong-field approximation (SFA) and a modified Coulomb-corrected SFA. Analytical expressions for the spin-resolved ionization rates are obtained and the scaling laws for the spin asymmetry and spin-flip parameters are derived. An intuitive explanation for the spin effects is given. It is shown that the intuitive picture supports the results for the spin effects obtained in the modified Coulomb-corrected SFA where the impact of the laser field on the electron spin evolution in the bound state is taken into account.
