摘要
The ac losses of Bi2223/Ag tapes were measured at 77K and under alternating magnetic field(50Hz) with the peak magnitude ranges from 0. 6 to 150mT. The samples were prepared by different process. It is found that the appropriate decreasing of temperature and time of the heat treatment can reduce ac losses. The subdivision of Bi2223/Ag tapes and the reduce of the thickness can also reduce ac losses. All of these belongs to the decrease of hysteresis loss.
