Description¶

ZF KuboToyabe when B = 0. A damped cosine precession when $B_int>0$ .

When B = 0,

$A(t)= A_0\left(\frac{1}{3}+\frac{2}{3}\cos(g_\mu B_0t)e^{-\sigma^2 t^2+\frac{2}{5}\Delta^2 t^2}\right) .$

When $B > 0$ ,

$A(t) = A_0\left(\frac13+\frac23(1-(\Delta t)^2)e^{-(\Delta t)^2/2}\right)$

where,

$A_0$ is the amplitude,

$\sigma$ (MHz) is the gaussian relaxation rate,

$B_0$ (G) is the gaussian relaxation rate,

and $\Delta$ is the relaxation rate of the extra term when $B>0$ .
