摘要：

Experimental data on the field and time dependencies of the isothermal magnetization for Tl and Bi 2212 single crystal are reported. It is shown that, due to some specific features of high-Tc superconductors, Bean-Livingston's surface barrier plays an unusual and important role in the processes of their magnetization. The values of the thermodynamic critical field for both substances are estimated. © 1990.
