Description:
Structure of the magnetic excitations in the spin-1/2 triangular-lattice Heisenberg antiferromagnet Ba 3 CoSb 2 O 9 Nature Communications, Published online: 10 August 2017; doi:10.1038/s41467-017-00316-x Two-dimensional frustrated magnets are heavily studied because theories predict that quantum effects may lead to the emergence of fractionalized excitations. Ito et al. use inelastic neutron scattering to show that the excitation spectrum of Ba 3 CoSb 2 O 9 disagrees with current theoretical expectations.
