.. index:: PCRmagnetZFKT
ZF signal from PCR ordered magnet with Kubo Toyabe field contribution
A(t)=A_0 \left(\frac13+\frac23e^{-(\Delta t')^2/2}\left(\cos(\Delta t)-\frac{\Delta^2}{\omega} t\sin(\omega t)\right)\right)\\
where,
\omega=g_\mu H_0 ,
t'=t-t_\text{off} ,
A_0 is the amplitude,
\Delta (MHz) is the relaxation rate,
H0 (G) is the local magnetic field,
g_\mu is the gyromagnetic ratio of muons,
and t_\text{off} (microsecs) is the time offset.
