摘要：

Further analysis of the resonant photoemission data, found within Sundar et al (2016 J. Phys.: Condens. Matter 28 315502), show the intensities do not follow the elemental composition in the Mo1-xRex alloy. Similar trends are observed in the published data for Gd1-xNix alloy films. The analysis of the resonant photoemission intensities suggests that Mo in the Mo1-xRex alloy and Gd in the Gd1-xNix alloy have nearest neighbor bonds to Re and Ni respectively. This means the A-B bond is favored over the average of the A-A bond and the B-B bond in these binary alloys, so that the short range order favors strong local ordering rather than clustering alloys.
