摘要：

The magnetic free energy is expanded in terms of exchange-induced magnetic fields. The second order term gives the bilinear coupling and the fourth order terms are shown to include the biquadratic coupling term. The coefficients of the expansion are expressed by using Green's functions, which make realistic calculations possible. The dependences of the biquadratic exchange coupling term on the spacer layer thickness and on temperature are examined in the single band tight-binding model.
