Magnetization measurements for La1.45Nd0.40Sr0.15CuO4 single crystal have been performed in order to investigate the effects of spin-charge ordering on pinning and scaling behavior of Jc and Pf. Despite the large differences in the irreversible fields along the ab-plane and the c-axis, the obtained values of Hc (hence the free energy) are basically similar. The maximum pinning forces obtained from the irreversible magnetization along c and in the ab-plane were found to scale with (Hc)β for both crystallographic directions.
