KünyeGüler, M., & Güler, E. (2014). High pressure phase transition and elastic behavior of europium oxide.
We report the questionable high pressure structural and elastic characteristics of europium oxide (EuO) up to 50 GPa with shell model potential framework by geometry optimization calculations. We determined B1→B2 phase transformation pressure of EuO as 43 GPa and a bulk modulus value as 106 GPa at zero Kelvin temperature under zero pressure. During search, we also determined the pressure dependence of typical cubic elastic constants, shear modulus, Young's modulus, elastic wave velocities, static and high frequency dielectric constants. Overall, our results show a fair agreement between experiments and competing with former theoretical findings.
