光照射フェライトメッキ法による Fe₃O₄ 膜の作製

抄録

Polycrystalline Fe₃O₄ films were plated on glass substrates in an aqueous solution. By irradiating the substrate surface with an Xe-lamp at ∼450 W/cm² power, the deposition rate of Fe₃O₄ film was increased by a factor of ∼10 (from ∼30 nm/min to ∼320 nm/min). With light exposures as short as 4 min we obtained ferrite films of ∼2μm thickness. We believe that the effect of the light is to raise the temperature. X-Ray analysis revealed that the films were polycrystalline spine1 with no preferred crystal orientation, scattering due to impurity phase being not observed.
