Abstract

Well-crystallized Y-type hexagonal ferrite (Me2-Y, Me=Zn and Co) films with highly c-axis orientation were successfully prepared on Ag substrates by dip coating technique. The procedure consisted of preparation of homogeneous metal-organic solution by polymerized complex method, dip coating and subsequent heat-treatment. The films deposited on α-Al 2O3 easily reacted with the substrate, while the films deposited on Ag formed hexagonal planar structures. The formation temperature of Me2-Y structures on Ag was 800 °C, which was much lower than that of Me2-Y bulk crystals. The Me2-Y films on Ag had a large in-plane magnetic anisotropy. The observed anisotropy field of the Zn 2-Y film was about 13 kOe and that of Co2-Y was too large beyond our experimental limits.
