The first ever pressure-dependence study has started at the Department of Physics. One of the goals of the UKF project Quantum CorES was to initiate the pressure research at the faculty, and we are happy to report that the first pressure mounting has been successful.
In the image to the left one can see two signals - an NQR signal of Cu2O powder measured at ambient pressure and at 8.15 kbar. The position of the line moves due to a change in ionic interaction of copper and surrounding oxygen, when the crystal cell is under stress.
Pressure is increased via hydrostatic compression, and the plan is to reach 26 kbar this summer.
To our great joy, the era of pressure research has begun at the Faculty of Science.
We thank our colleague P. Popčević from the Institute of Physics who helped us in preparation of this experiment.
