Abstract
DC magnetization measurements were carried out on YBaCuO prepared by the quench and melt-growth (QMG) process using a vibrating sample magnetometer and a SQUID magnetometer below 100 K. It was found that the DC magnetization behavior of QMG-grown YBaCuO at 4.2 K can be quantitatively explained in terms of Bean´s critical state model. This sample also can become a strong bulk permanent magnet with an energy product of more than 80 MGOe at 5 K because of its strong pinning force.
