H3LiIr2O6

H3LiIr2O6 is a material considered to best fit the archetype for being a special type of quantum spin liquid called a Kitaev spin liquid. Though known not to freeze at cold temperatures, H3LiIr2O6 is notoriously difficult to produce in a lab and is known to have disorder in it, muddying whether it was truly a spin liquid.

H3LiIr2O6 is considered to be a spin liquid that is proximate to the Kitaev-limit quantum spin liquid. Its ground state shows no magnetic order or spin freezing as expected for the spin liquid state. However, hydrogen zero-point motion and stacking faults are known to be present.
