“…In order to improve magnetic properties and/or to obtain the c-axis oriented La-CoBaM films, the La-CoBaM films were coated on under-layer. To achieve the c-axis oriented BaM films, many kinds of under-layers such as Pt, AlN, ZnO and SiO 2 have been investigated [2,3,[5][6][7]. In this study, we selected the (111) oriented Pt thin films for under-layer.…”

La-Co substituted BaM (La-CoBaM) thin films have been prepared by a sol-gel technique involving a spin coating of metal-organic compounds. We report the effects of Pt under-layer on the c-axis orientation of La-CoBaM films and their magnetic properties. On the Pt under-layer with the thickness of 120 nm whose 111 axis oriented perpendicular to substrate surface, the La-CoBaM films with the thickness ranging from 20 to 95 nm were coated at room temperature. These coated films were annealed at 900ºC for 5h. in air. The Hc ┴ /Hc // value for the La-CoBaM films with the thickness of 20 nm was 3.9 that was the largest of all samples. The c-axis of magnetoplumbite phase was oriented perpendicular to the film surface, that was caused by the effect of the (111) oriented Pt under-layer.
