Magnetic excitation spectrum of a potential spin liquid candidate

DOI

PbCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu ions. There are 3 potentially strong interactions, the first neighbor interaction couples the magnetic ions into isolated triangles, the second couples them into the highly frustrated hyperkagome lattice consisting of corner sharing triangles and the third neighbor interaction couples them into antiferromagnetic chains. In PbCuTe2O6 the hyperkagome interaction dominates suppressing long-range magnetic order making it a promising spin liquid (SL) candidate. The fundamental excitations of a SL are expected to be spinons which are fractional (spin-1/2) excitations and are observed in inelastic neutron scattering (INS) as broad and diffuse features rather than the sharp modes typical of magnons or spin-waves. In this context, we wish to explore the magnetic excitations of PbCuTe2O6 using INS on LET spectrometer.
