The results show that there are two peaks in the imaginary part corresponding to the grains and grain boundaries in the sintered sample, but only one peak is observed in that of MTG sample of high quality. As for that of MTG sample of worse quality, also two peaks are observed, but they correspond to grains with different growth direction. No frequency effect is observed in both the sintered sample and the MTG sample, showing that the loss is related to flux motion. %K MTG法 %K 超导体 %K 磁化率 %K 高Tc %K YBaCuO %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=47EA7CFDDEBB28E0&jid=29DF2CB55EF687E7EFA80DFD4B978260&aid=1150A4EB01A57B37EF4DE3465EF6C97E&yid=F53A2717BDB04D52&vid=2001E0D53B7B80EC&iid=0B39A22176CE99FB&sid=A2745AA1110798CA&eid=EC34D52BE81085CE&journal_id=1000-3290&journal_name=物理学报&referenced_num=0&reference_num=5
