VOCl at low temperature

What is it about?

VOCl develops magnetic order below TN=80.3(3) K. The magnetic phase transition is accompanied by a small, temperature-dependent monoclinic lattice distortion, the phase transition presumably is of second order.

Why is it important?

The lattice distortion is not accompanied by a structural distortion so that the driving force for the lattice distortion is completely governed by the magnetic interactions.
