摘要：

Recent progress in material processing has enabled the fabrication of large single grain YBCO bulks having the potential to trap a magnetic field much stronger than that of conventional permanent magnets, thus opening the way to new applications in the field of power electric machinery. However, for YBCO bulks to find a broad use, a suitable magnetization process must be developed. In fact, the value of the trapped field as well as the stability with respect to the time and the shape of the profile strongly depend on the parameters of the magnetization process, i.e. the peak value and the waveform of the applied field and the operating temperature of the bulk. In this paper such a dependence is numerically investigated.
