Description

We report on the heteroepitaxial deposition of La1-xSrxMnO3 (LSMO) thin films using RF and DC magnetron sputtering. Co-deposition from the two different LSMO targets with x=0.25 and x=0.35 was used to tailor the desired composition to control ferromagnetic Curie temperature of the films. The influence of different single crystalline substrates as well as the effect of varying the oxygen partial pressure on magnetic and structure properties during deposition was investigated. The chemical stoichiometry was determined by Rutherford backscattering spectroscopy (RBS). Transmission electron microscopy and high resolution X-ray diffractometry (HRXRD) confirmed epitaxial growth for substrates with low in-plane lattice mismatch. The temperature dependence of the electric resistance agrees with the TCurie determined by (zero) field-cooling (FC/ZFC) superconductive quantum interference device SQUID measurements.
