    In the paper:

    D.C. Jiles, "Dynamics of domain magnetization and the Barkhausen effect,
    Czechoslovak Journal of Physics", Vol 50 (2000). pp. 893-988.

    Jiles give a simply version of his model that can be integrated without
    the implicity of the factor dMirr/dt. However if you have the barkhausen
    signal of the Material which is ->dMirr/dt then you can solve the equation
    by nolinear fitting instead of use integration.
