The phase and microstructure of strips and ingots were studied by scanning electron microscope (SEM) and X-ray diffraction (XRD). The microstructure of strips showed dendritic crystalline structure. The texture was observed by XRD analysis. Further, microstructure and elements distribution of magnets made with strips and ingots were comparatively studied by transmission electron microscope (TEM) and energy dispersive spectrometer (EDS). Smaller cellular structure was observed in the magnets made with strips. According to the EDS analysis, Gd element homogeneously distributes in the cellular structure, while Dy element tends to distribute in the cell wall phase. By using precursor strips, temperature coefficient of remanence and energy product of sintered magnets is optimized from -0.015%/<sup>°</sup>C and 15.76 MGOe to -0.01%/<sup>°</sup>C and 16.39 MGOe.</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 chemical analysis; X-ray diffraction; casting; cobalt alloys; copper alloys; crystal microstructure; dysprosium alloys; gadolinium alloys; iron alloys; rapid solidification; remanence; samarium alloys; scanning electron microscopy; sintering; transmission electron microscopy; zirconium alloys; EDS; SEM; Sm<sub>0.7</sub>Dy<sub>0.1</sub>Gd<sub>0.2</sub>(CoFe<sub>0.2</sub>Cu<sub>0.08</sub>Zr<sub>0.025</sub>)<sub>7.2</sub>; TEM; X-ray diffraction; XRD; cellular structure; dendritic crystalline structure; element homogeneously; energy dispersive spectrometer; magnetic properties; microstructure; rapidly solidified strips; remanence temperature coefficient optimization; scanning electron microscopy; sintered magnets; strip-casting technique; transmission electron microscopy; Microstructure; Perpendicular magnetic anisotropy; Remanence; Saturation magnetization; Strips; Temperature; Magnetic materials; SmCo; materials processing; remanence temperature coefficient; strip-casting technique;</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.2013.2274961</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'>6570517</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=60386' target='_blank'>https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=60386</a></div> </div> </div> <div class='leftDiv labelDiv leftAlign backLinkEnglish'><a href='javascript:history.back()'><img src='../CSS/Back.png' class='backImage' alt=
