Abstract
The mechanism of the pressure-induced ferroelastic phase transition in rutil-like NiF is discussed within a simple lattice dynamical model2. It is found that the phenomenon in question can be completely assigned to softening of single B1g mode and can be regarded as intrinsic property of the rutile family.Keywords
