Structural characterization and magnetoresistance of manganates thin films and Fe-doped manganates thin films

摘要

Perovskites thin films with the composition La0.6Ca0.4MnO3 doped with 20% Fe, were prepared by pulsed reactive crossed beam laser ablation, where a synchronized reaction gas pulse interacts with the ablation plume. The films were grown on various substrates and the highest colossal magnetoresistance ratio (CMR) was detected by Hall measurements for films grown on LaA1O(3) (1 0 0), which was selected as substrate for further investigations.
