Magnetization measurements have been performed on Mg1xAlxB2 (0 ≤ x ≤ 0.1) at various temperatures below Tc and in fields up to 9 T. The reversible magnetization has been used to calculate the thermodynamic critical field (Hc) which is then used to obtain a new universal behavior for both the critical current density (Jc) and the pinning force (Pf). This approach is based on vortex core energy (∼H2c) and clearly exhibits the deviation from single vortex pinning with increasing temperature and higher concentration of Al-doping.
