►Calculation of spin relaxation time due to non-uniform magnetic field is presented. ► A calculation of the linear-in-electric-field frequency shift is also developed. ► Results are valid in the diffusion approximation for a rectangular cell geometry. ► An example application of a dipole impurity near the cell is shown.
A method is presented to calculate the spin relaxation times
