Abstract
We carried out neutron powder diffraction experiments on the cluster-based Haldane compound fedotovite K2Cu3O-(SO4)3. Weak magnetic reflections caused by a magnetic long-range order appeared below an antiferromagnetic transition temperature TN = 3.1 K. We propose a possible magnetic structure that is consistent with the magnetic properties reported in the literature.

Preliminary neutron powder diffraction measurements at the CTAX spectrometer used resources at the High Flux Isotope Reactor, a DOE Office of Science User Facility operated by the Oak Ridge National Laboratory (ORNL), U.S.A. (proposal ID. 2018-06). Follow-up neutron powder diffraction experiments were performed by using the SIKA spectrometer at Australian Nuclear Science and Technology Organisation (ANSTO), Australia (proposal ID. P6939). Business travel expense for the CTAX experiments was supported by the US-Japan cooperative program for neutron scattering. We are grateful to T. Hong, M. Matsuda, H. Mamiya, M. Nishino, N. Terada, N. Tsujii, M. Fujihala, and T. Sugimoto for fruitful discussion and to S. Matsumoto for the sample syntheses and X-ray diffraction measurements.
