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…
Magnetic properties of vanadium-oxide nanotubes probed by static magnetization and {51}V NMR
E. Vavilova, I. Hellmann, V. Kataev +3
Measurements of the static magnetic susceptibility and of the nuclear magnetic resonance of multiwalled vanadium-oxide nanotubes are reported. In this nanoscale magnet the structur…
Tuning the magnetic ground state of a novel tetranuclear Nickel(II) molecular complex by high magnetic fields
C. Golze, A. Alfonsov, R. Klingeler +10
Electron spin resonance and magnetization data in magnetic fields up to 55 T of a novel multicenter paramagnetic molecular complex [L_2Ni_4(N_3)(O_2C Ada)_4](Cl O_4) are reported.…
High-field ESR studies of the quantum spin magnet CaCu2O3
M. Goiran, M. Costes, J. M. Broto +6
We report an electron spin resonance (ESR) study of the s=1/2-Heisenberg pseudo-ladder magnet CaCu2O3 in pulsed magnetic fields up to 40 T. At sub-Terahertz frequencies we observe…
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…
Giant positive magnetoresistance in metallic VOx thin films
A. D. Rata, V. Kataev, D. Khomskii +1
We report on giant positive magnetoresistance effect observed in VOx thin films, epitaxially grown on SrTiO3 substrate. The MR effect depends strongly on temperature and oxygen con…
