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.
