CompositePCRmagnet

Description

ZF KuboToyabe when B = 0. A damped cosine precession when Bint>0 .

When B = 0,

A(t)=A0(13+23cos(gμB0t)eσ2t2+25Δ2t2).

When B>0 ,

A(t)=A0(13+23(1(Δt)2)e(Δt)2/2)

where,

A0 is the amplitude,

σ (MHz) is the gaussian relaxation rate,

B0 (G) is the gaussian relaxation rate,

and Δ is the relaxation rate of the extra term when B>0 .
