Paper Abstract

The possibility of using the pulsed laser deposition technique to produce garnet (Y3Fe5O12) and ferrite (Mn1- xZnxFe2O4) thin films of high quality on different substrates (poly-Al2O3, poly-AlN, sapphire) is explored. The properties of thin films prepared by excimer laser ablation of stoichiometric non-sintered (Y3Fe5O12) and sintered (Mn1-xZnxFe2O4) ceramic targets are performed. The stoichiometrical transfer from targets to substrates, as well as synthesis of YIG phase in the case of ablation of non-sintered Y3Fe5O12 target is achieved. The magnetic measurements in two in-plane perpendicular each to other directions are carried out. The hysteresis loops observed show evidence of anisotropy which depends on the crystal structure of substrates. The typical values of coercive force and saturation magnetization measured appear to be comparable to those of more thick films. The films are characterized by VSM and XPS analyses.
