Four perovskite compounds ATbO3 (A = Fe, Cr, Al, Co) are studied by means of neutron diffraction. Three Nèel temperatures are distinguished. When A is magnetic and T < TN1, the A sublattice orders in a G mode; when T < TN2, the Tb sublattice orders and is coupled with A in the same irreducible representation of the space group Pbnm; finally when T < TN3, Tb orders in another mode which is decoupled from A, i.e., Tb orders in a different irreducible representation. The order in the latter case is the only one observed one if A is diamagnetic, and its origin is mainly dipolar. The Néel temperatures are given; the metamagnetism of Tb is studied for T < TN3.
