Spinon continuum in the Heisenberg quantum chain compound Sr${}_2$V${}_3$O${}_9$

Shang Gao, Ling-Fang Lin, Pontus Laurell +11

Magnetic excitations in the spin chain candidate Sr${}_2$V${}_3$O${}_9$ have been investigated by inelastic neutron scattering on a single crystal sample. A spinon continuum with a bandw…
