摘要：
A theoretical description of dynamic properties of the disordered Heisenberg-Ising ferromagnets has been proposed. By the configurational averaging of the equation of motion for spins, the dynamic susceptibility has been derived. It has been shown that all the basic magnetic properties of disordered systems can be studied from the dynamic susceptibility. A generalisation of the fluctuation-dissipation theorem for the case of disordered magnets has been made. The main numerical results have been illustrated in the figures and a detailed discussion has been given.
