D.C. 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 77K. It was found that the D.C. magnetization behavior of QMG processed YBaCuO at 4.2 K can be quantitatively explained in terms of Bean model. This sample also can become a strong bulk permanent magnet with a maximum energy product exceeding 80MGOe at 5 K due to its large pinning force.
