Proton disorder in the double hydroxide perovskite CuSn(OH)6 under hydrostatic pressure
We have identified a transition-metal hydroxide perovskite that combines correlated proton disorder with geometrically frustrated S=1/2 magnetism of Cu2+ ions. We expect that similarly to water ice, the proton network in CuSn(OH)6 may order under hydrostatic pressure. Therefore we are interested in measuring neutron diffraction under pressure in the Paris-Edinburgh cell up to ~5 GPa at temperatures down to ~80 K to look for structural changes in the proton network. Both deuterated and protonated phase-pure powder samples are already available. If any such changes are revealed, their influence on magnetic properties will be addressed in follow-up studies.
