Abstract
In this paper, the electronic transport of La0.7(Sr,Ca)0.3MnO3 films grown by pulsed laser deposition on a LaAlO3(001) substrate with deep parallel structured steps and a 30° symmetric bicrystal SrTiO3(001) substrate have been discussed. The electronic transport properties have been related to the well-known extrinsic transport of bulk manganite compounds. The spin-glass-like behavior with a characteristic peak at 20 K and domain formation at the grain boundary is observed. Further, it has been quantified from the resonant tunneling model that mixed magnetic interactions play a significant role in the manganite films deposited on step edges.
