PCRmagnetZFKT¶
Description¶
ZF signal from PCR ordered magnet with Kubo Toyabe field contribution
\[\begin{split}A(t)=A_0 \left(\frac13+\frac23e^{-(\Delta t')^2/2}\left(\cos(\Delta t)-\frac{\Delta^2}{\omega} t\sin(\omega t)\right)\right)\\\end{split}\]
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.
