Abstract

Two superconducting Nb-47wt%Ti composites with island shaped Ti5wt%Nb artificial pinning centers (APC) have been made. The Ti5wt%Nb volume fractions in the composites are 10% and 20% respectively. The bulk flux pinning force curves of the APC NbTi composites at 4.2K have been studied. The results show that as the pin size is reduced F_pmax increases and moves to higher magnetic fields. The behavior of the bulk flux pinning force curves of the Ti5wt%Nb APC NbTi composites are better than those of Nb APC NbTi composites, in that F_pmax occurs at a higher magnetic field.
