AFMZF¶
Description¶
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.
