Oxygen Isotope Exchange

A colossal shift of the maximum resistivity temperature induced by oxygen isotope exchange was registered for 60 nm thick films of the solid solution La0·35Pr0·35Ca0·3MnO3 on perovskite substrates. The magnitude of the effect depends on lattice strain resulting in the largest shift for the film on LaAlO3: the 16O sample showed a metal-insulator transition at 182 K, whereas the 18O sample was insulating down to 4·2 K, which is the highest difference ever reported for CMR manganites. An XRD and Raman spectrometry study indicates no difference in chemical composition or structure for the 18O and 16O samples at room temperature. The results are consistent with the model coupling the metal-insulator transition in the perovskite manganites to the lattice dynamics.
