High temperature ferromagnetism of Li-doped vanadium oxide nanotubes
A. I. Popa, E. Vavilova, Y. C. Arango +7
The nature of a puzzling high temperature ferromagnetism of doped mixed-valent vanadium oxide nanotubes reported earlier by Krusin-Elbaum et al., Nature 431 (2004) 672, has been ad…
Interplay of Rare Earth and Iron magnetism in RFeAsO with R = La, Ce, Pr, and Sm: A muon spin relaxation study and symmetry analysis
H. Maeter, H. Luetkens, Yu. G. Pashkevich +11
We report zero field muon spin relaxation (muSR) measurements on RFeAsO with R = La, Ce, Pr, and Sm. We study the interaction of the FeAs and R (rare earth) electronic systems in t…
Superconductivity and Field-Induced Magnetism in SrFe_1.75Co_0.25As_2
R. Khasanov, A. Maisuradze, H. Maeter +7
Using muon-spin rotation, we studied the in-plane (λ_ab) and the out of plane (λ_c) magnetic field penetration depth in SrFe_1.75Co_0.25As_2 (T_c=13.3 K). Both λ_ab(T) and λ_c(T) a…
Orbital and spin effects for the upper critical field in As deficient disordered Fe pnictide superconductors
G. Fuchs, S. -L. Drechsler, N. Kozlova +17
We report B_c2 data for LaO_{0.9}F_{0.1}FeAs_{1-delta} in a wide T and field range up to 60 Tesla. The large slope of B_c2 approx ~ -6 Tesla/K near an improved T_c = 28.5 K of the…
