“…The most significant effect of doping is achieving better performances in the magnetic field that makes MgB 2 a superconductor for practical applications [14][15][16]. Chemical doping materials affect vibrating movements of the atoms by interchanging with the main atoms, and therefore superconducting properties changes [17,18]. The most important problem in chemical doping addition is the impurities coming out of as a result of the interaction of doping materials with Mg and B atoms [19,20].…”
