Spin relaxation and linear-in-electric-field frequency shift in an arbitrary, time-independent magnetic field

Abstract:
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.

In spin–lattice or longitudinal relaxation, the excited spins exchange energy with the surrounding lattice as they return to the lower energy level. Among several mechanisms that contribute to spin–lattice relaxation, magnetic dipolar interactions are significant. Here, the excited nucleus transfers energy to a nearby...
