- Abstract
We present measurements of resistivity ρ in highly oriented LaNiO films grown on LaAlO substrates by using a pulsed laser deposition technique. The experimental data are found to follow a universal ρ( T) ∝ T dependence for the entire temperature interval (20 K T 300 K). The observed behavior has been attributed to a resonant scattering of electrons on antiferromagnetic fluctuations (with a characteristic energy hω ≃ 2.1 meV) triggered by spin-density wave propagating through the interface boundary of LaNiO/LaAlO sandwich.
