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.

Name	Default	Description
A0	1.0
Hloc	0.1	Local magnetic field (G)
