Schematic picture of the structure with Co1 in octahedral and Co2 in pyramidal sites. Oxygen vacancies are forming channels in the direction.
HERDA spectrum of the film , measured at the recoil energy of .
X-ray diffraction pattern in radial directions close to the points (0 0 2), (0 0 ) and (0 1) of reciprocal space. The notation used corresponds to the primitive perovskite unit cell. The scans were collected using Cu (a), (b) and Co (c) x-ray tubes. The arrows mark the and substrate peaks. Scans (a) and (b) were normalized to the intensity of the (0 0 2) substrate peak. Scans for the films , , and were multiplied by factors of 10, , and , respectively, in order to separate them in the plot.
Magnetic moment of the films , , , and vs temperature and magnetic prehistory ( cooled, field cooled).
Temperature dependences of dc resistance of the films , , , above room temperature. The inset shows the resistance of film in the wide temperature region of 150–380 K.
Unit cell parameters of the polycrystalline target and substrates.
Preparation conditions, unit cell parameters, and relative oxygen content of the films . The oxygen content was calculated assuming in the film . The relative error of the oxygen concentration is in our case on average based on counting statistics.
