摘要
We demonstrate the growth of epitaxial Fe/Ba(Fe1-xCox-2As2 bilayers on MgO(001) and (La, Sr)(Al, Ta)O-3(001) single crystal substrates using pulsed laser deposition (PLD). This architecture produces a coherent interfacial bond between body-centered cubic iron and Bs(Fe1-xCox)(2)As-2 (Ba-122). The superconducting transition temperatures for both bilayers remain close to that of the PLD target. Direct observation of interfacial bonding between Fe and the Ba-122 FeAs sublattice by atomic resolution transmission electron microscopy implies that this bilayer architecture may work for other iron pnictide systems and pave the way for their fabrication into superconducting/ferromagnetic heterostructures.
