We have prepared magnetic bioglass ceramics (MBC) by annealing 41CaO·44 SiO<sub>2</sub>·4P<sub>2</sub>O<sub>5</sub>·8Fe<sub>2</sub>O<sub>3</sub>·3Na<sub>2</sub>O glass at temperatures ( TA) ranging from 750 <sup>°</sup>C to 1150 <sup>°</sup>C for 1 h. X-ray diffraction patterns confirm the presence of bone mineral (hydroxyapatite and wollastonite) and magnetite ( Fe<sub>3</sub>O<sub>4</sub>) phases in nanocrystalline form in the MBCs. Average crystallite size ( d<sub>av</sub>) of all the phases increased with increasing T<sub>A</sub>. Magnetization ( M-H) curves of all MBCs were recorded up to 20 kOe at 300 K to understand the evolution of magnetism in the nonmagnetic glass upon heat treatment. Magnetic properties correlated with d<sub>av(magnetite)</sub> for samples annealed up to 1050 <sup>°</sup>C. Electron paramagnetic resonance study was carried out to understand the behavior of sample annealed at 1150 <sup>°</sup>C and the evolution of magnetic properties in the MBCs. This study also reveals a methodology to control the magnetic properties of this MBC and its potential application in hyperthermia treatment of bone cancer.</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 diffraction; annealing; bioceramics; calcium compounds; cancer; crystallites; glass ceramics; iron compounds; magnetic hysteresis; materials preparation; paramagnetic resonance; patient treatment; phosphorus compounds; silicon compounds; sodium compounds; CaO-P<sub>2</sub>O<sub>5</sub>-Na<sub>2</sub>O-Fe<sub>2</sub>O<sub>3</sub>-SiO<sub>2</sub>; X-ray diffraction; annealing; bone mineral; cancerous tissue; crystallite size; hydroxyapatite; implanted thermoseed; local heat treatment; magnetic biocompatible material; magnetic bioglass ceramics; magnetic hysteresis loss; magnetic properties; magnetism; magnetite; magnetization curves; nanocrystalline form; nonmagnetic glass; temperature 300 K; temperature 750 degC to 1150 degC; time 1 h; wollastonite; Glass; Heat treatment; Heating; Iron; Magnetic hysteresis; Magnetic resonance; Saturation magnetization; Biomaterials; biomedical applications; electron paramagnetic resonance; glass-based composites;</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.2013.2278570</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'>6693019</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=39247' target='_blank'>https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=39247</a></div> </div> </div> <div class='leftDiv labelDiv leftAlign backLinkEnglish'><a href='javascript:history.back()'><img src='../CSS/Back.png' class='backImage' alt=
