摘要
The interaction of magnetic colloidal particles includes the interaction of colloidal particles and the interaction of the moment of magnetism.The interaction of the moment of magnetism is regard as perturbation.According to the low density system of magnetic colloidal particles in water,a theoretic model is set up based on perturbation theory.The relations between internal energy,specific heat of magnetic colloidal particles system and temperature,density of colloidal particles are calculated.The calculated results are useful in explaining the magnetic memory effect.
