The temperature (T) dependent double integrated intensity (DI) and peak to peak linewidth provide the estimation of charge ordering (CO) temperature T<sub>CO</sub>, long-range antiferromagnetic (AFM) onset temperature, T<sub>O</sub>, ordering temperature, T<sub>N</sub>, and the information about the magnetic interactions. The T<sub>CO</sub> values are 317 K, 317 K, 321 K, and 311 K for undoped, V, Cu, and Zn doped samples, respectively. It is noticed that V doping sharpens the CO transition, whereas Cu and Zn doping smears the CO transition. The temperature dependent magnetization measurements support the ESR observations. In the temperature range T >; T<sub>CO</sub>, ferromagnetic (FM) correlations dominate. In the temperature range T<sub>CO</sub> >; T >; T<sub>O</sub>, the samples are in the paramagnetic (PM+CO) phase. The AFM interactions dominate in the doped samples in this temperature range. The orbital ordering (OO) sets in progressively with decreasing temperature leading to onset of long-range AFM ordering at ~ 200 K for undoped and in the range 190-170 K for doped samples. The present study shows the strong competition between FM and AFM correlations as a function of temperature and composition of the sample.</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'>antiferromagnetic materials; bismuth compounds; calcium compounds; doping; exchange interactions (electron); ferromagnetic materials; magnetic variables measurement; magnetisation; paramagnetic materials; paramagnetic resonance; Bi<sub>0.5</sub>Ca<sub>0.5</sub>Mn<sub>0.95</sub>Cu<sub>0.05</sub>O<sub>3</sub>; Bi<sub>0.5</sub>Ca<sub>0.5</sub>Mn<sub>0.95</sub>V<sub>0.05</sub>O<sub>3</sub>; Bi<sub>0.5</sub>Ca<sub>0.5</sub>Mn<sub>0.95</sub>Zn<sub>0.05</sub>O<sub>3</sub>; ESR; charge ordering temperature; doping; electron spin resonance; ferromagnetic correlations; long-range antiferromagnetic onset temperature; magnetic interactions; orbital ordering; paramagnetic phase; temperature 190 K to 170 K; temperature dependent double integrated intensity; temperature dependent magnetization measurements; transition element substitution; Copper; Doping; Frequency modulation; Temperature dependence; Temperature distribution; Temperature measurement; Zinc; Magnetic domains; magnetic materials; magnetic resonance;</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.2011.2148166</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'>6028128</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=1331794' target='_blank'>https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=1331794</a></div> </div> </div> <div class='leftDiv labelDiv leftAlign backLinkEnglish'><a href='javascript:history.back()'><img src='../CSS/Back.png' class='backImage' alt=$
