Structural and magnetic studies of the alkali sesquioxides Rb4O6 and Cs4O6
The mixed-valence sesquioxides A4O6 (A = alkali metal) are particularly intriguing magneticmaterials comprising of non-magnetic (O2)2- and magnetic (O2)- anions. Recent... -
Quantum-Critical Dynamics of a 3-dimensional Antiferromagnet
We have recently discovered a pressure-induced quantum phase transition (QPT) at 4.3 kbar in the gapped quantum magnet piperazinium hexachlorodicuprate (PHCC) by means of...
