The Growth was done (in the presence of O2 at a pressure of 0.3mbar) using PLD and the cooling starts at 675oC after deposition until room temperature at 20oC/min (with increasing O2 pr from 0.3mbar to 200mbar during cooling) . I want to know the possible effect the intensity of Secondary peaks (Bi2O3/Fe2O3) might have because of quick cooling (20oC/min instead of 10oC/min cooling rate).
