Redfield¶
Description¶
The Redfield formula for the LF dependence on the muon spin relaxation rate.
\[\Lambda(t)= \frac{2\gamma^2_\mu H^2_\text{loc}\tau}{1+\gamma^2_\mu H^2_\text{LF} \tau^2}\]
where,
\(H_\text{loc}\) 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.
