A ferromagnetic particle with single domain, at some
kinds of applied field (at some angle or strangth), the
particle's free energy would be two state model. The
rate of barrier crossing could be solve by Fokker-Planck
equation .And use master equation to find out the Total
rate between two potential well.
In this thysis, we use the upper method to simulate
particle's magnetic moment under time varying magnetic
field at fixed angle or fixed magnetic applied rotate
the particle.
In numerical method, we use the back Euler method
to prevent the divergence of the calculation.
