Pressure effects on the zigzag ladder antiferromagnet b-CaCr2O4
The zigzag antiferromagnet beta-CaCr2O4 exhibits an excitation spectrum characterized by an unusual pseudo-gapped signal above TN, thought to arise from the contribution of a two-spinon continuum. A distribution in the Cr-Cr distances can account for this pseudo-gap. As applying an external pressure on the system would allow to tune the Cr-Cr distances, we would like to study the effect of high pressure on the crystallographic and magnetic structure of b-CaCr2O4.
