Resumen:
The optimization of MgB2 superconducting properties is extremely important for practicalapplication. The introduction of an effective artificial pinning center in this material can enhance itscritical current density efficiently. In this paper, VB2 is described as a material that provides effectivepinning in the MgB2 bulks. The simultaneous addition of SiC as a carbon source is also analyzed.The samples were prepared using ball milling under a controlled atmosphere and heat treatment witha continuous argon flux. As a result, the superconducting properties could be optimized due to theeffective improvement in the pinning behavior as well as with the carbon doping.
