Abstract
We have investigated the differences in (magneto-)resistance, magnetism and morphology of thin films of La0.73Ca0.27MnO3, grown by sputter deposition in high oxygen pressure on substrates of either SrTiO3 or LaAlO3. We find that growth on SrTiO3 is epitaxial and sooth, in contrast to growth on LaAlO3, where islands are formed at low coverage, leading to rough and disordered films at higher coverage. This type of deposition appears to lead to different film morphology than films grown by laser ablation.
