To improve the interface magnetism of Co <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">x</sub> Fe <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3-x</sub> O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> (CFO) films that are grown on MgO substrates and exhibit extremely large perpendicular magnetic anisotropy, we attempted to insert two different spinel-type oxides [CoCr <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> (CCO) and MgTi <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> (MTO)] between the CFO films and their MgO(001) substrates. Although both buffer layers were epitaxially grown on MgO(001), the CFO films grown on CCO/MgO(001) became polycrystalline with a significantly lower level of magnetization, while the magnetization of the CFO films on MTO/MgO(001) fell as a function of the thickness of the MTO layer. A secondary ion mass spectroscopy analysis revealed a remarkable interdiffusion of Co and Mg.
