摘要：

We present a spin-orbital model for doped La(1-x)Sr(x)MnO(3) which describes the superexchange between S = 2 (S = 3/2) spins and explains the observed A-type antiferromagnetic ordering and anisotropic exchange constants in LaMnO(3). The doping dependence of the exchange constants suggests that the orbital ordering does not change as long as the e(g) holes are localized. (C) 1999 Elsevier Science B.V. All rights reserved.
