Abstract

Flux pinning mechanism in superconducting NbTi composites with Ti5wt%Nb artificial pinning center is analyzed in detail. The results show that F_p(B) mainly depends on normal metal pinning mechanism and Δκ pinning mechanism. The results suggest that both normal metal pinning mechanism and Δκ pinning mechanism are very important. The value of F_p(B) in lower magnetic field is mainly dominated by normal metal pinning mechanism and the value of F_p(B) in higher magnetic field is mainly dominated by Δκ pinning mechanism. The function value of F_p(B) dependant on normal metal pinning mechanism and Δκ pinning mechanism increase respectively with the decrease of the wire diameter.
