Anomalies caused in the lattice properties of band magnetic materials by features of the electronic structure
Irkhin V. Yu., Katsnel'son M. I., Trefilov A. V.
Particular features of the electronic structure of band magnetic materials near the Fermi level play an important role in the magnetovolume and magnetoelastic anomalies. Explicit expressions are derived for the corresponding contributions to the thermal expansion coefficient and the elastic moduli. An explanation is proposed for the anomalies observed in ZrZn2 and Cr.
