摘要	For magnetic materials with exchange interaction, A = A(1) + A(2) (A(1) > 0, A(2) < 0), the dominant term in the exchange energies of magnetic materials (A(1) for ferromagnetism, or A(2) for antiferromagnetism) favors to an order of the spins, whereas the minor term with different sign (A(2) for ferromagnetism or AI for antiferromagnetism) tends to disturb such order, and the effect of the minor term could be included as an effective temperature (Teff). The magnetism of a matter depends on the competition between the dominant term and the minor term in the exchange energies. When A(1) = \A(2)\, A = 0, the materials are in the spin glass state; when A(1) > \A(2)\, there is the coexistence of FM and SG; when \A(2)\ > A(1), there is the coexistence of AFM and SG. The phase diagram has been derived based on the ratio of A(1)/\A(2)\ for the ferromagnetism, antiferromagnetism and spin glass. (C) 2002 Elsevier Science Ltd. All rights reserved.
