Abstract
We propose a mechanism for A-type antiferromagnetism in orthorhombic L aMnO3, compatible with the large Jahn-Teller splitting inferred from s tructural data. Orbital ordering resulting from Jahn-Teller distortion s effectively leads to layered ordering (antiferromagnetic in the c ax is and ferromagnetic in the ab plane) provided the in-plane distortion Q(2) is large enough, a condition generally fulfilled in existing dat a.
