Zusammenfassung:[Display omitted] ►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 T 1, T 2 due to a non-uniform magnetic field, and the linear-in-electric-field precession frequency shift δω E when an electric field is present, in the diffusion approximation for spins confined to a rectangular cell. It is found that the rectangular cell geometry admits of a general result for T 1, T 2, and δω E in terms of the spatial cosine-transform components of the magnetic field. The result is applied to the case of a permanently-magnetized dipole impurity near the cell.
