Incommensurate atomic density waves in the high-pressure IVb phase of barium

Incommensurate atomic density waves in the high-pressure IVb phase of barium

The host–guest structures of elements at high pressure discovered a decade ago still leave many open questions due to the lack of precise models based on full exploitation of the diffraction data. This concerns in particular Ba IV, which is stable in the range 12–45 GPa. With the example of phase Ba...
