Synthesis of Homogeneous Manganese-Doped Titanium Oxide Nanotubes from Titanate Precursors
Péter Szirmai, Endre Horváth, Bálint Náfrádi +6
We report a novel synthesis route of homogeneously manganese-doped titanium dioxide nanotubes in a broad concentration range. The scroll-type trititanate (H(2)Ti(3)O(7)) nanotubes…
Signatures of quantum criticality in the thermopower of Ba(Fe(1-x)Co(x))2As2
S. Arsenijević, H. Hodovanets, R. Gaál +3
We demonstrate that the thermopower (S) can be used to probe the spin fluctuations (SFs) in proximity to the quantum critical point (QCP) in Fe-based superconductors. The sensitivi…
Testing the Elliott-Yafet spin-relaxation mechanism in KC8; a model system of biased graphene
Gábor Fábián, Balázs Dóra, Ágnes Antal +6
Temperature dependent electron spin resonance (ESR) measurements are reported on stage 1 potassium doped graphite, a model system of biased graphene. The ESR linewidth is nearly is…
