SrCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu ions. The 1st, 2nd and 3rd neighbor interactions respectively couple Cu2+ into a network of isolated triangles,a highly frustrated hyperkagome lattice consisting of corner sharing triangles and antiferromagnetic chains. Of these, the chain interaction dominates in SrCuTe2O6 while the other two interactions lead to frustrated interchain coupling giving rise to long range magnetic order, however, at suppressed temperatures. This is in contrast to ideal spin-1/2 antiferromagnetic chain which is expected to have a spin liquid ground state with no long-range magnetic order and spinon excitations. Frustrated interchain coupling leads to weak long-range order and modifies the low energy excitation spectrum in a way that reflects the underlying physics arising from the frustration. Therefore, we wish to explore the magnetic excitations of this quantum magnet using inelastic neutron scattering on the THALES spectrometer together with the multiplexed analyzer/detector and the single detector systems. Hence, we request a beamtime of 7 days.
