SpinGlass

Description

Fitting function for use by Muon scientists defined by:

A(t)=A0(13eΩt+23(1Qa2t2Ωt+Qa2t2)eΩt+Qa2t2)
Ω=4(1Q)a2ν

where,

A0 is the amplitude,

Q is the order parameter,

ν is the rate of Markovian modulation,

and a is the half-width half maximum of the local field Lorentzian Distribution.

Note that 0<q<1 and γ>0
