Description

ZF signal from PCR ordered magnet

A(t)=A_0\left(\frac{1}{3}+\frac{2}{3}e^{-(\sigma\omega t')^2/2}\cos(\omega t)\right)

where,

\omega=g_\mu H_0 ,

t'=t-t_\text{off} ,

A_0 is the amplitude,

\sigma (MHz) is the relaxation rate,

H0 (G) is the local magnetic field,

g_\mu is the gyromagnetic ratio of muons,

and t_\text{off} (microsecs) is the time offset.

.. plot::

   from mantid.simpleapi import FunctionWrapper
   import matplotlib.pyplot as plt
   import numpy as np
   x = np.arange(0.1,16,0.1)
   y = FunctionWrapper("PCRmagnet")
   fig, ax=plt.subplots()
   ax.plot(x, y(x))
   ax.set_xlabel('t($\mu$s)')
   ax.set_ylabel('A(t)')
