摘要：

Field-cooled magnetization measurements on the monophasic polycrystalline superconductor (Er0.2Ca0.8)Sr2(Tl0.5Pb0.5)Cu2Oy (Tc = 105 K) under various magnetic fields between 5.0 and 130 K are reported. For the cooling field Ha < 17 gauss, the strong paramagnetism induced by the trapped flux was observed. This novel effect is significantly different from the more familiar diamagnetic shielding of a superconductor. © 1990.
