Behavior of the Curie temperature of EuO at pressures up to 20 GPa
Tissen V. G. , Ponyatovskii E. G.
A sharp change has been detected in the behavior of the Curie temperature of EuO at 13 GPa. It is attributed to a transition of EuO to a mixed-valence state. The stability of the ferromagnetism in the mixed-valence phase of EuO is discussed.
