ORIENTED THIN FILMS FORMATION IN A PHOTO-MAGNETIC COMPLEX FIELD

抄録

Using a diacrylate monomer as an ablation source, containing some additives such as cobalt (Co) and aluminum nitride(AlN) powders we prepared thin films by Nd:YAG laser in a 8 teslas magnetic field. When we prepared an about 3μm thick thin film by laser ablation, a rate of thin film formation increased about thirty times comparing the case used as a target with adding to Co particles of 10% in weight with that of used crude material . We suggest that heat conductivity of raw material increased on the imaginary with adding Co particles. And as the amount of Co particles increases, a rate of thin film formation increased. The properties of raw material and thin film were measured by near, intermediate and polarized FT-IR, Energy dispersive spectroscopy (EDS) and scanning electron microscope (SEM) and so on. It was found that polymerization of diacrylate monomer were carried out by intermediate FT-IR and Co element wasn't measured in thin film by EDS. Moreover polarized IR spectroscopy measurement showed that thin film formed by laser ablation using a target with Co particles had molecular orientation in plane of carbonyl and methylene groups as well as using crude material.
