DampedBessel¶
Description¶
A bessel function with damped oscillation that could apply to incommensurate magnetic structures or spin density waves.
where,
\(A_0\) is the amplitude of asymmetry,
\(J_0(x)\) is the Bessel function of the first kind,
\(\lambda_\text{T}\) is the damping of the oscillation,
\(\lambda_\text{L}\) is the dynamic longitudinal spin relaxation rate,
\(B\) (G) is the B-field,
and \(\phi\) is the phase.
