Redfield

Description

The Redfield formula for the LF dependence on the muon spin relaxation rate.

\Lambda(t)= A_0\frac{2\gamma^2_\mu H^2_\text{loc}\tau}{1+\gamma^2_\mu H^2_\text{LF} \tau^2}

where,

A_0 is the amplitude of asymmetry,

H_\text{loc} is the local magnetic field,

H_\text{LF} is the longitudinal magnetic field applied,

and its expression is given as \tau = \frac{1}{f} where f is the frequency of fluctuation at muon sites.
