Bond disorder and breakdown of ballistic heat transport in the spin-1/2 antiferromagnetic Heisenberg chain as seen in Ca-doped SrCuO2
N. Hlubek, P. Ribeiro, R. Saint-Martin +9
We study the impact of a weak bond disorder on the spinon heat transport in the S=1/2 antiferromagnetic (AFM) Heisenberg chain material Sr_{1-x}Ca_xCuO_2. We observe a drastic supp…
Disorder-induced Spin Gap in the Zigzag Spin-1/2 Chain Cuprate Sr_{0.9}Ca_{0.1}CuO_2
F. Hammerath, S. Nishimoto, H. -J. Grafe +6
We report a comparative study of 63Cu Nuclear Magnetic Resonance spin lattice relaxation rates, T_1^{-1}, on undoped SrCuO_2 and Ca doped Sr_{0.9}Ca_{0.1}CuO_2 spin chain compounds…
Ballistic heat transport of quantum spin excitations as seen in SrCuO2
N. Hlubek, P. Ribeiro, R. Saint-Martin +5
Fundamental conservation laws predict ballistic, i.e., dissipationless transport behaviour in one-dimensional quantum magnets. Experimental evidence, however, for such anomalous tr…
Magnetization of undoped 2-leg S = 1/2 spin ladders in La4Sr10Cu24O41
R. Klingeler, I. Hellmann, P. Ribeiro +2
Magnetization data of single crystalline La4Sr10Cu24O41 are presented. In this compound, doped spin chains and undoped spin ladders are realized. The magnetization, at low temperat…
One- and Two-Triplon Spectra of a Cuprate Ladder
S. Notbohm, P. Ribeiro, B. Lake +12
We have performed inelastic neutron scattering on the near ideal spin-ladder compound La4Sr10Cu24O41, which will serve as a model system for the investigation of doped ladders. A k…
Current spinon-holon description of the one-dimensional charge-transfer insulator SrCuO2: Angle-resolved photoemission measurements
A. Koitzsch, S. V. Borisenko, J. Geck +6
We have investigated the low-energy electronic structure of the strongly correlated one-dimensional copper oxide chain compound SrCuO2 by angle resolved photoemission as a function…
