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…

Nanoscale electronic order in iron pnictides

G. Lang, H. -J. Grafe, D. Paar +5

The charge distribution in RFeAsOF (R=La, Sm) iron pnictides is probed using As nuclear quadrupole resonance. Whereas undoped and optimally-doped or overdoped compounds…

Interplay of Magnetic Exchange Interactions and Ni-S-Ni Bond Angles in Polynuclear Nickel(II) Complexes

Yulia Krupskaya, Alexey Alfonsov, Anupama Parameswaran +7

The ability of bridging thiophenolate groups to transmit magnetic exchange interactions between paramagnetic Ni(II) ions has been examined. For this purpose, dinuclear and trinucle…

Indications for a line of continuous phase transitions at finite temperatures connected with the apparent metal-insulator transition in 2d disordered systems

A. Mobius

In a recent experiment, Lai et al. [Phys. Rev. B 75 (2007) 033314] studied the apparent metal-insulator transition (MIT) of a Si quantum well structure. Tuning the charge carrier c…
