Abstract
Neutron scattering measurements have been performed on deuterated powder samples of claringbullite and Zndoped claringbullite [ZnxCu4−x (OD)6FCl]. At low temperatures, claringbullite Cu4(OD)6FCl forms a distorted pyrochlore lattice with long-range magnetic order and spin-wave-like magnetic excitations. Partial Zn doping leads to the nominal ZnCu3(OD)6FCl compound, a geometrically frustrated spin-1/2 kagome antiferromagnet that shows no transition to magnetic order down to 1.5 K. The magnetic excitations form a gapless continuum, a signature of fractional excitations in a quantum spin liquid.
