The crossing of the magnetization M of cuprates in different fields at (M*, T*) has been widely interpreted as a result of 2D vortex-fluctuations. Therefore, it is expected that the M* T* of HgBa2CamCum + 1 Oy will be proportional to the 2D sheet-density 1 s, where s is the size of the unit cell. However, our data show that the M* T* is independent of both m and s in the Hg-based cuprates with 1 ≤ m ≤ 3. A survey further suggests that the value of M* T* is a universal constant for all studied Bi-, Tl- and Hg-based cuprates. This observation suggests that the coupling between neighboring CuO2-blocks may have non-negligible effects on the magnetization.
