. Layer and substrate both have the same magnetoplumbite type crystal structure. Static magnetic properties of the layers compared to literature values for bulk crystals of the same chemical composition are reported. They provide evidence for potential applications in the bubble domain technique and microwave and millimeter-wave devices.
