    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
