Our work does not support a general view that A-site deficiency gives a decrease on Curie temperature. The Curie temperature of (La<sub>0.8</sub>Ca<sub>0.2</sub>)<sub>0.975</sub>MnO<sub>3.01</sub> is 188 K with maximum entropy change -ΔSM <sub>max</sub> = 1.6 J·kg<sup>-1</sup>·K<sup>-1</sup> and refrigerant capacity (RC) of 27 J/kg under an applied field of 10 kOe. The nonstoichiometric (La<sub>0.8</sub>Ca<sub>0.2</sub>)<sub>0.975</sub>MnO<sub>3.01</sub> may offer a wider temperature span of ~240% compared with those nanocrystalline La<sub>0.8</sub>Ca<sub>0.2</sub>MnO<sub>3.01</sub> that have similar RC, which has been reported by others.</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'>Curie temperature; calcium compounds; entropy; lanthanum compounds; magnetic cooling; nanofabrication; nanomagnetics; nanostructured materials; stoichiometry; (La<sub>0.8</sub>Ca<sub>0.2</sub>)<sub>0.975</sub>MnO<sub>3.01</sub>; A-site deficiency; Curie temperature; magnetocaloric effect; manganite perovskite; maximum entropy change; nanocrystalline material; nonstoichiometry; refrigerant capacity; solid-state reaction technique; Compounds; Entropy; Lattices; Magnetic properties; Magnetization; Metals; Temperature measurement; $A$ -site deficiency; magnetocaloric effect; nonstoichiometric;</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.2013.2292075</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'>6798025</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=78320' target='_blank'>https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=78320</a></div> </div> </div> <div class='leftDiv labelDiv leftAlign backLinkEnglish'><a href='javascript:history.back()'><img src='../CSS/Back.png' class='backImage' alt=$
