dc.description.abstractWe have employed Co K-edge extended x-ray absorption fine structure measurements with linear polarization dependence to investigate the chemical short-range order (SRO) and interatomic distance anisotropy in CoxPd1-x alloy (X = 0.16, 0.31) and [Co(2 Angstrom)/Pd(Y Angstrom)](13) multilayer films (Y = 15, 32). The SRO parameters of in-plane first nearest neighbors, 0.063-0.068 in the alloys and 0.012-0.036 in the multilayers, are observed. Surprisingly, these counterintuitive results show clear evidence that the Co atoms at the Co/Pd interfaces in multilayers have more alloylike characteristic than those in alloys with respect to local chemical environment.-
dc.description.sponsorshipS.K.K is indebted to R. Ynunza for his careful review of this manuscript. The EXAFS measurements were performed on the EXAFS beamline of SSRC, Novosibirsk, Russia. This work was supported by Pohang Accelerator Laboratory, POSTECH, and the Creative Research Initiatives of the Korean Ministry of Science and Technology.en
