SrCuO2 is a prototypical S = 1/2 antiferromagnetic (AF) Heisenberg 1D spin chain system. High-resolution neutron scattering studies has already successfully revealed the gapless low-energy spin excitations down to 0.5 meV energy transfer. However, recently and very surprising it was found, from magnetic transport measurement, that by adding a minuscule amount of Ni impurities a gap opens in the magnetic excitation spectrum of SrCu(1-x)NixO2. From NMR data such gap was estimated as ~9 meV, but the origin of the gap is presently very unclear. To the best of our knowledge, no neutron spectroscopy studies have been performed on the doped compound and our the first aim will be to obtain a detailed overview of the low-energy spin excitation spectrum (up to 75 meV) for a SrCu(1-x)NixO2 single crystal with 1% Ni content. Further, we propose to make a detailed T-dependence of the gap energy.
