Phys. Rev. B 54, 11762–11768 (1996)Evidence for a strain-stabilized bct phase of cobalt deposited on Pd{100}: An x-ray photoelectron diffraction studyReceived 14 February 1996; published in the issue dated 15 October 1996 The structure of cobalt layers grown on a Pd{100} single-crystal surface has been studied by scanned angle x-ray photoelectron diffraction. At room temperature the cobalt layers grow in a structure related to the bulk cobalt fcc phase characterized by a large expansion of the in-plane lattice parameters and a corresponding contraction of the interlayer spacing (∼10%). This structure persists to coverages greater than 30-layer equivalents, and can be interpreted as a metastable body-centered-tetragonal (bct) phase. © 1996 The American Physical Society. © 1996 The American Physical Society URL:
