Laser synthesis of new materials

The dual-beam laser ablation of different targets for synthesizing new materials within the overlapping plasma area has been investigated. This method is termed ‘laser synthesis of new materials’ and it is flexible in tuning the composition of the new materials by varying the targets, the laser fluence on each target and the input gas as well as the substrate position within the overlapping plasma area. A new Ba–Fe–Y–O magnetic material has been synthesized by this method, which can be written as BaOkFe2-xYxO3, where k is either 6 or 11 and x is about 0.4 or 0.9 for BaFe9.2Y2.6O20 or BaFe12.3Y9.6O33.3 material. Both materials are permanent magnets and have hexagonal structure. The lattice parameters a and c are 0.551 nm and 2.337 nm for BaFe9.2Y2.6O20 and 0.747 nm and 2.332 nm for BaFe12.3Y9.6O33.3, respectively.
