Comment on 'Electronic structure of Mo(1-x)Re x alloys studied through resonant photoemission spectroscopy'.

ABSTRACT

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-x Re x alloy. Similar trends are observed in the published data for Gd1-x Ni x alloy films. The analysis of the resonant photoemission intensities suggests that Mo in the Mo1-x Re x alloy and Gd in the Gd1-x Ni x 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.
