- Abstract
- The perovskite compound La0.67Ce0.33MnO3 (LCeMO) is a candidate for electron doping rather than the hole doping common in manganites. However, it is not clear whether Ce, which has a smaller ionic radius than other dopants, can be incorporated into the crystal lattice. Thin LCeMO films were prepared by two different deposition techniques. In both cases, a chemical phase separation is observed, which in one case leads to a self-organized columnar nanostructure with no indication for n-type doping. In the other case, we find hole doping induced by La vacancies.
