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…

X-ray absorption spectroscopy on layered cobaltates Na_xCoO_2
T. Kroll, M. Knupfer, J. Geck +7
Measurements of polarization and temperature dependent soft x-ray absorption have been performed on Na_xCoO_2 single crystals with x=0.4 and x=0.6. They show a deviation of the loc…

Quenched charge disorder in CuO2 spin chains: Experimental and numerical studies
R. Leidl, R. Klingeler, B. Buechner +2
We report on measurements of the magnetic response of the anisotropic CuO_2 spin chains in lightly hole-doped La_x (Ca,Sr)_14-x Cu_24 O_41, x>=5. The experimental data suggest that…
