Spin Gap in the Single Spin-1/2 Chain Cuprate SrCaCuO
F. Hammerath, E. M. Brüning, S. Sanna +7
We report Cu nuclear magnetic resonance and muon spin rotation measurements on the S=1/2 antiferromagnetic Heisenberg spin chain compound SrCaCuO. An exp…
Bond disorder and spinon heat transport in the Heisenberg spin chain compound SrCuO: from clean to dirty limits
A. Mohan, N. Sekhar Beesetty, N. Hlubek +4
We investigate the effect of disorder on the heat transport properties of the Heisenberg chain compound SrCuO upon chemically substituting Sr by increasing…
Spin pseudogap in Ni-doped SrCuO2
G. Simutis, S. Gvasaliya, M. Mansson +11
The S=1/2 spin chain material SrCuO2 doped with 1% S=1 Ni-impurities is studied by inelastic neutron scattering. At low temperatures, the spectrum shows a pseudogap Δ~ 8 meV, absen…
Evidence of d-wave Superconductivity in K_(1-x)Na_xFe_2As_2 (x = 0, 0.1) Single Crystals from Low-Temperature Specific Heat Measurements
M. Abdel-Hafiez, V. Grinenko, S. Aswartham +20
From the measurement and analysis of the specific heat of high-quality K_(1-x)Na_xFe_2As_2 single crystals we establish the presence of large T^2 contributions with coefficients al…
Low temperature ballistic spin transport in the S=1/2 antiferromagnetic Heisenberg chain compound SrCuO2
H. Maeter, A. A. Zvyagin, H. Luetkens +7
We report zero and longitudinal magnetic field muon spin relaxation measurements of the spin S=1/2 antiferromagnetic Heisenberg chain material SrCuO2. We find that in a weak applie…
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…
