dc.description.abstractThis study reports the effect of coronene (C24H12) addition on some superconducting properties such as critical temperature (T (c) ), critical current density (J (c) ), flux pinning force density (F (p) ), irreversibility field (H (irr) ), upper critical magnetic field (H (c2) ), and activation energy (U (0) ), of bulk MgB2 superconductor by means of magnetisation and magnetoresistivity measurements. Disk-shaped polycrystalline MgB2 samples with varying C24H12 contents of 0, 2, 4, 6, 8, 10 wt%, were produced at 850 A degrees C in Ar atmosphere. The obtained results show an increase in field-J (c) values at 10 and 20 K resulting from the strengthened flux pinning, and a decrease in critical temperature (T (c) ) because of C substitution into MgB2 lattice, with increasing amount of C24H12 powder. The H (c2) (0) and H (irr) (0) values are respectively found as 144, 181, 172 kOe, and 128, 161, 145 kOe for pure, 4 wt% and 10 wt% C24H12 added samples. The U (0) depending on the magnetic field curves were plotted using thermally activated flux flow model. The maximum U (0) values are respectively obtained as 0.20, 0.23 and 0.12 eV at 30 kOe for pure, 4 wt% and 10 wt% C24H12 added samples. As a result, the superconducting properties of bulk MgB2 at high fields was improved using C24H12, active carbon source addition, because of the presence of uniformly dispersed C particles with nanometer order of magnitude, and acting as effective pinning centres in MgB2 structure.en_US
