摘要：

The remanent magnetic flux density trapped in the cavity and in the wall of sintered tubes of Y-Ba-Cu-0 and Bi-Sr-Ca-Cu-0 was measured as a function of H(cool), the axial magnetic field present during field cooling and then removed, and of H(cycle), the axial magnetic field impressed and removed after zero-field cooling. For both procedures the two specimens exhibit very different behavior. A simple critical-state model which takes into account the return field of the magnetized grains quantitatively reproduces all of our observations and the corresponding data reported by others.
