摘要：

We propose a mechanism for A-type antiferromagnetism in orthorhombic LaMnO3, compatible with the large Jahn-Teller splitting inferred from structural data. Orbital ordering resulting from Jahn-Teller distortions effectively leads to layered ordering (antiferromagnetic in the c axis and ferromagnetic in the ab plane) provided the in-plane distortion Q(2) is large enough, a condition generally fulfilled in existing data.
