INS investigation of post-pressurised Cs2CuCl4

Abstract: Cs2CuCl4 has been extensively studied using neutron scattering, and has revealed a quantum spin liquid phase below 2.8 K with antiferromagnetic interactions, and long range magnetic order below 0.62 K. Intriguingly, it has now been shown that when single crystals are subjected to 5kbar of hydrostatic pressure for 2 days, upon releasing the pressure, long range magnetic order is instead observed up to 9 K, yet X-ray diffraction has revealed no clear structural changes. Potentially post-pressurised Cs2CuCl4 is less frustrated with a more quasi-one-dimensional antiferromagnetic spin 1/2 ordered magnetic state, and therefore we aim to investigate the effects of post pressurisation on the excitation spectrum to gain an insight into how the magnetic interactions have been modified.
