Abstract

Multiferroic BiFeO3 epitaxial films were fabricated on SrTiO3 (100) substrates by a chemical solution deposition method. Magnetic layers of Co, Py, Co40Fe40B20, Co 75Fe25, and Co50Fe50 were then deposited by sputtering under a magnetic field. Despite employing a chemical process, a clear exchange bias was observed for all the magnetic materials. The temperature dependence of Hex was evaluated for a Co 50Fe50/BiFeO3 bilayer having a relatively large Hex and high squareness. The Hex of Co 50Fe50/BiFeO3 bilayer increased between 10 to 250 K.
