Detecting percolative metal-insulator transition in manganites by resistive relaxation

X. J. Chen, H. -U. Habermeier, C. C. Almasan

We report an experimental study of the time dependence of resistivity of a La${}_{0.9}$Sr${}_{0.1}$MnO${}_3$ ultrathin film in order to elucidate the underlying mechanism for metal-ins…
