1201.6474 (ALain Pautrat et al.)

Magnetoresistance, noise properties and the Koshino-Taylor effect in the
quasi-1D oxide KRu_4O_8
   [PDF]

ALain Pautrat, Wataru Kobayashi
The low temperature electronic and galvanomagnetic transport properties of
the low dimensional oxide KRu_4O_8 are experimentally considered. A quadratic
temperature variation of the resistivity is observed to be proportional to the
residual resistivity. It shows the role of inelastic electron scattering
against impurities, i.e. a large Koshino-Taylor effect, rather than a
consequence of strong electronic correlations. In the same temperature range,
the Kohler rule is not fulfilled. The resistance noise increases also sharply,
possibly due to a strong coupling of carriers with lattice fluctuations in this
low dimensional compound.
