Magnetic tunnel junctions (MTJ) were fabricated using Al-O insulating layers prepared on epitaxial Ni80Fe20 (NiFe) bottom electrode. Fewer defects were expected in an insulator grown on the epitaxial bottom electrode than one on the textured bottom electrode. The result indicated that output signals of the devices based on MTJ could be enhanced by improving insulating layer quality.
