Unidirectional Diagonal Order and 3D Stacking of Charge Stripes in Orthorhombic Pr1.67Sr0.33NiO4 and Nd1.67Sr0.33NiO4
M. Huecker, M. v. Zimmermann, R. Klingeler +9
The interplay between crystal symmetry and charge stripe order in Pr1.67Sr0.33NiO4 and Nd1.67Sr0.33NiO4 has been studied by means of single crystal x-ray diffraction. In contrast t…
Spin Susceptibility in Underdoped Cuprates: Insights from a Stripe-Ordered Crystal
M. Huecker, G. D. Gu, J. M. Tranquada
We report a detailed study of the temperature and magnetic-field dependence of the spin susceptibility for a single crystal of La(1.875)Ba(0.125)CuO(4). From a quantitative analysi…
Dzyaloshinsky-Moriya Spin Canting in the LTT Phase of La2-x-yEuySrxCuO4
M. Huecker, V. Kataev, J. Pommer +4
The Cu spin magnetism in La2-x-yEuySrxCuO4 (x<=0.17; y<=0.2) has been studied by means of magnetization measurements up to 14 T. Our results clearly show that in the antiferromagne…
The Local Structure of La1.65Eu0.2Sr 0.15CuO4 determined by 63Cu NMR Spectroscopy and Van Vleck Paramagnetism of Eu3+ Ions
Barbara Simovic, Markus Huecker, P. Chris Hammel +3
We investigate the local symmetry of the tilting of the CuO octahedra in LaEuSrCuO by means of Cu NMR spectroscopy and the Va…
