Abstract
The effect of oxygen pressure and laser pulse duration on the production of thin films of La0.7Sr0.3CoO3-delta (LSC) and La0.7Sr0.3Co0.2Fe0.8O3-delta (LSCF) by laser ablation has been investigated. Evidence of reduction and p hase separation of the target surfaces was found by X-ray diffraction. Abla tion of LSC, at low oxygen partial pressures and with an excimer laser, led to the production of poor quality films, compared with the LSCF. This is a ttributed to the greater stability of LSCF in terms of low oxygen pressures . (C) 2000 Published by Elsevier Science B.V.
