Abstract

The pinning force density, Fp, of a new type of Nb artificial pin was observed in Nb-46.5 wt.% Ti superconducting wires, where the artificial pins were made of thin Nb plates inserted into successive NbTi plates and were cold drawn to a ribbon-like shape. It is shown that the position of the peak of Fp shifts systematically from the low magnetic field side to the high-field side as the reduction rate of pin thickness increases. The flux pinning mechanism of the pins is also discussed.
