dc.description.abstract© 2016 Taylor & Francis Group, LLC. In this work, we used density functional theory to study the structures, formation energy and order–disorder structural transition temperature (To) of L10FePt with Ag additive. The results show that an Ag atom substituting for a Fe site is more energetically preferable than that of substituting for a Pt, thus Ag atom should replace Fe site. We found that Tois significantly suppressed by Ag impurity because of the increasing in configurational entropy, whereas the magnetism tends to decrease due to the absence of some Fe atom in doping processes. The decrease in Tocould open the opportunity to prepare FePt with lower temperature and small grain size for the high density magnetic recording media application.en_US
