Four-well tunneling states and elastic response of clathrates

I. Zerec, V. Keppens, M. A. McGuire +3

We present resonant ultrasound elastic constant measurements of the clathrate compounds Eu8Ga16Ge30 and Sr8Ga16Ge30. The elastic response of the Eu clathrate provides clear evidenc…

Metallic "Ferroelectricity" in the Pyrochlore Cd2Re2O7

I. A. Sergienko, V. Keppens, M. McGuire +8

A class of materials known as ``ferroelectric metals'' was discussed theoretically by Anderson and Blount in 1965 [Phys. Rev. Lett. 14, 217 (1965)], but to date no examples of this…
