We show that substitution of the rare-earth (Ho, Er) by a non-magnetic one (Y, Lu) acts as a simple magnetic dilution effect. In contrast, the magnetic properties of these systems are drastically changed when Fe is substituted by the non-magnetic Al, independently of the rare-earth involved. The combined study of the different regions of the absorption spectra for the different atomic species in these materials allow us to disentangle the structural and electronic effects of the substitution. Our results reveal that the change of the magnetic properties upon Al substitution are triggered by the strong modification of the density of states (DOS) which also affects the R(5<i>d</i>)-Fe(3<i>d</i>) hybridization.</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Keywords : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>X-ray absorption spectra; aluminium alloys; electronic density of states; erbium alloys; holmium alloys; iron alloys; lutetium alloys; magnetic moments; yttrium alloys; Er<sub>1-x</sub>Lu<sub>x</sub>(Fe<sub>1-y</sub>Al<sub>y</sub>)<sub>2</sub>; Er<sub>1-x</sub>Y<sub>x</sub>(Fe<sub>1-y</sub>Al<sub>y</sub>)<sub>2</sub>; Ho<sub>1-x</sub>Lu<sub>x</sub>(Fe<sub>1-y</sub>Al<sub>y</sub>)<sub>2</sub>; Ho<sub>1-x</sub>Y<sub>x</sub>(Fe<sub>1-y</sub>Al<sub>y</sub>)<sub>2</sub>; X-ray absorption spectroscopy; XAS; aluminium substitution effect; density of states; disentangle; electronic structure; hybridization; magnetic dilution effect; magnetic interactions; magnetic moments; magnetic properties; rare-earth metal; transition metal; Intermetallic compounds; Laves phase compounds; X-ray absorption spectroscopy; magnetic materials;</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>fLanguage : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>English</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Journal_Title : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>Magnetics, IEEE Transactions on</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Publisher : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>ieee</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>ISSN : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>0018-9464</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Type : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>jour</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>DOI : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>10.1109/TMAG.2008.2001315</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Filename : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>4717655</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Link To Document : </div><div class='valueDiv leftDirection leftAlign fullRecValueEnglish col-xs-8 col-sm-10'><a href='https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=3560294' target='_blank'>https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=3560294</a></div> </div> </div> <div class='leftDiv labelDiv leftAlign backLinkEnglish'><a href='javascript:history.back()'><img src='../CSS/Back.png' class='backImage' alt=
