Zheludev The S =1/2 spin chain material SrCuO 2 doped with 1% S =1 Ni impurities is studied by inelastic neutron scattering. At low temperatures, the spectrum shows a pseudogap Δ ≈8 meV, absent in the parent compound, and not related to any structural phase transition. The pseudogap is shown to be a generic fea... [Phys.
