Abstract

We report experimental results of phase stability and incompressibility of CrN. The obtained bulk moduli for cubic and orthorhombic CrN are 257 and 262 GPa, respectively. These results invalidate the conclusion of phase-transition-induced elastic softening recently reported based on nonmagnetic simulations for cubic CrN. On the other hand, they provide the only experimental evidence to support the computational models involving the local magnetic moment of Cr atoms, indicating that atomic spin has a profound influence on the material's elastic properties. We also demonstrate that nonstoichiometry in CrN x has strong effects on its structural stability.
