Author(s): Yannic Utz, Franziska Hammerath, Satoshi Nishimoto, Christian Hess, Neela Sekhar Beesetty, Romuald Saint-Martin, Alexandre Revcolevschi, Bernd Büchner, and Hans-Joachim Grafe The S = 1 / 2 antiferromagnetic Heisenberg spin chain compound Sr 2 CuO 3 doped with 1 % and 2 % of Ni impurities has been studied by means of Cu 63 nuclear magnetic resonance. A strong decrease of the spin-lattice relaxation rate T 1 − 1 at low temperatures points toward a spin gap, while a stretching exponent … [Phys. Rev. B 92, 060405(R)] Published Mon Aug 10, 2015
