Space and time resolved emission spectroscopy of Sr2FeMoO6 laser induced plasma
In this work the plasma dynamics induced during pulsed Nd:YAG (lambda = 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 x 10(-5) mbar of O-2 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. (c) 2005 Elsevier B.V. All rights reserved.
