摘要

Pd/Co/Pd tri-layer films were prepared on MgO substrates of (001), (111), and (011) orientations at room temperature by ultra high vacuum rf magnetron sputtering. The detailed film structures around the Co/Pd and the Pd/Co interfaces are investigated by reflection high energy electron diffraction. Pd layers of (001 )_(fcc), (111)_(fcc), and (011)_(fcc) orientations epitaxially grow on the respective MgO substrates. Strained fcc-Co(001) single-crystal layers are formed on the Pd(001 )_(fcc) layers by accommodating the fairly large lattice mismatch between the Co and the Pd layers. On the Co layers,, Pd polycrystalline layers are formed. When Co films are formed on the Pd( 111 )_(fcc) and the Pd(011 )_(fcc) layers, atomic mixing is observed around the Co/Pd interfaces and fcc-CoPd aL1_0y phases are coexisting with Co crystals. The Co crystals formed on the Pd( 111 )_(fcc) layers consist of hcp(0001)+fcc( 111) and Pd( 111 )_(fcc) epitaxial layers are formed on the Co layers. Co crystals epitaxially grow on the Pd(011)_(fcc) layers with two variants, hcp(L1_0O) and fcc(111). On the Co layers, Pd(011)_(fcc) epitaxial layers are formed.
