Magnetic correlations in a quantum critical S = 1/2 spin ladder system
Spin ladders are excellent model systems for studying quantum phase transitions, as they exhibit a quantum critical point between non-magnetic spin singlet dimers to Néel magnetic order as inter-ladder exchange is increased. Ba2CuTeO6 is a Cu2+ S = 1/2 two-leg spin ladder system, that is close to the quantum critical point on the Néel ordered side. By replacing Te with W in a Ba2CuTe1-xWxO6 solid solution, we have managed to tune the system to quantum criticality with a potential spin liquid state. We will use polarised neutron diffraction with XYZ analysis to study magnetic correlations in these compositionally tuned samples. This will allow us to study how this affects correlations within the ladders and between them, and to better understand the possible spin liquid state.
