Enhanced superconducting properties of Eu2O3-doped MgB2

Effect of graphene oxide doping on superconducting properties of bulk MgB2

“…carbohydrates [11][12][13], B 4 C [14], carbon-nanotubes [15], SiC [16] has been reported to be effective in improving superconducting properties such as H irr , H c2 and J c under high magnetic fields. In addition to carbon, doping of rare earth oxides [17,18], co-doping of rare earth and carbon [13] and magnetic nanoparticles [19] have also been found to be effective in improving the superconducting properties of MgB 2 . In the case of carbon doping it has been found that carbon substituted at boron sites increases intra-band impurity scattering, leading to an enhancement in H c2 and a decrease in T c .…”

Study of superconducting properties of ferrocene‐added MgB2

“…However, carbon doping introduces an extra electron in the conduction band of MgB 2 , which reduces the hole density‐of‐states and leads to a reduction of the critical temperature, T C . In addition to carbon, addition of rare‐earth oxides and dispersed magnetic nanoparticles into MgB 2 have shown improvements in J C ( H ) and the irreversibility field, H irr . Magnetic element substitution has always been considered to suppress superconductivity because it hinders Cooper pair formation, but it has been found that the effect of magnetic element substitution is the same as that of a non‐magnetic element in case of a multi‐band gap superconductor .…”

Computational Intelligence Approach for Estimating Superconducting Transition Temperature of Disordered MgB2Superconductors Using Room Temperature Resistivity

“…Its economic affordability as well as its unique properties offers it a special place in practical applications despite its low as compared with high temperature superconductors. The techniques that are usually employed for improving the superconducting properties of MgB 2 include introduction of disorder through chemical doping and several thermomechanical processing techniques which alter its room temperature resistivity [3,5,[7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. In order to improve the superconducting properties of this material (in particular ), we develop STTE for accurate, quick, and direct estimation of of disordered MgB 2 superconductors as an alternative to conventional method which is experimentally intensive.…”
