Abstract

Magnetic shielding properties have been investigated using Hall plates at 4.2 K in a parallel magnetic field up to 4 T for superconducting cylinders with and without a bottom, which are multilayer composites consisting of NbTi, Nb, and Cu. These composite cylinders were fabricated by deep drawing a multilayer composite sheet made by cladding and rolling. It was found that a sample of five concentrically stacked cup-shaped cylinders, with a thickness of 1 mm, an inside diameter of 20-40 mm, and a length of 45 mm, can reduce the external magnetic field of 3 T to less than 10 G.<>
