Description
We report magnetic investigations of a novel Kagome-related compound. Single crystals of the compound Cu2OSO4 have been studied by neutron scattering, magnetization and susceptibility. We find that instead of the spin-liquid ground state expected for a kagome compound, Cu2OSO4 orders in a canted anti-ferromagnetic structure. The magnetic structure is solved through neutron diffraction. The phase diagram established through susceptibility and specific heat measurements. Inelastic neutron spectra are being analyzed to determine the magnetic exchange pathways, and eventually explain the observed behavior.
