.. index:: AFMZF
ZF oscillation for aligned Anti-ferromagnetic magnetic sample with Gaussian dephasing
A(t) = \frac{A_0}{2}((1-a_1)+a_1\cos(\omega_1t+\phi))+(1-a_2)+a_2\cos(\omega_2t+\phi))
where,
a_1 =\sin^2\theta ,
\omega = 2\pi\nu ,
\nu is the ZF frequency (MHz),
\sigma is the Gaussian relaxation for oscillatory component,
\theta is the angle of internal field w.r.t. to applied field,
and \phi is the phase.
