What is Spin Relaxation?

At thermal equilibrium, the spins have a Boltzmann distribution, with more α spins than β spins. The return to equilibrium is the process called spin relaxation. Spin relaxation is the return of a spin system to equilibrium. It is of two types - Longitudinal and transverse relaxation.
