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.
