摘要: The effect on crystal structure, critical temperature (TC), and current density (JC) of bulk MgB2 doped with nano-Ho2O3 naphthalene was studied. Among all the samples studied, sample 2.5 wt. % have shown best field dependent [JC(H)], i.e., 0.77 × 105 A/cm2 at 2 T 10 K. While has least JC(H) characteristics. improved characteristics in are attributed to flux pinning properties due formation HoB4 samples. slight lower TC value (37.01 K) is occurrence lattice defect by substitution carbon boron site superconductor. Lower ΔTC implies lesser anisotropy synthesized force (FP/FPmax) curves theoretically analyzed using Dew-Hughes model. result revealed that point d...
