PCRmagRedfield

Description

ZF signal from PCR ordered magnet with Redfield Fluctuations.

A(t)= \begin{cases} A_0\left(\frac13+\frac23e^{-\frac{\Delta^4}{q}t}\cos{\omega t}\right), & q\geq 0 \\ A_0\left(\frac13+\frac23\cos{\omega t}\right), & \text{otherwise} \end{cases}

where,

q=\nu(\nu^2+\Delta^2) ,

\omega = 2\pi\Delta ,

A_0 is the amplitude,

\lambda (MHz) is the relaxation rate,

and \Delta is the precession frequency.
