Show affiliationsKDy(MoO4)2 is known to undergo a structural phase transition at 14.3K. Spectroscopic and magnetic studies of the behaviour of this compound at low temperatures have revealed some striking properties which suggest that the phase transition is of the Jahn-Teller type and that ordering occurs in an antiferrodistortive mode. A two-sublattice molecular-field model has been developed to account qualitatively for the observed phenomena. This is thought to be the first reported instance of antiferrodistortive Jahn-Teller ordering in a rare-earth compound.
