Space and time resolved emission spectroscopy of Sr2FeMoO6 laser induced plasma

In this work the plasma dynamics induced during pulsed Nd:YAG (λ = 532 nm) laser ablation of Sr2FeMoO6 targets has been studied by time- and space-resolved optical emission spectroscopy measurements in the range 250-650 nm. The integral intensities of spectral lines were measured as a function of distance from the target surface and laser fluence in the presence of 5 × 10−5 mbar of O2 partial pressure. The plasma properties as well as ionic and atomic Strontium time-of-flights were measured as a function of laser fluence in the range 0.90-2.40 J cm−2. The results show how the different plasma features can influence the film deposition process and the magnetic saturation properties.
