摘要：

The field-amplitude H-m and circular frequency v dependent ac susceptibility, chi=chi' - j chi", of a hard superconducting cylinder with flux-flow type current-voltage characteristic is calculated. A remarkable feature of the resultant chi(H-m, omega) is that both the maximum chi(n), chi(n)(m), and d lg H-m(chi(n)(m))/d lg omega increase with increasing omega. This behavior is observed in actual Bi-2223/Ag tapes and YBa2Cu3O7-delta-coated conductors. Our result provides a useful tool to study the intergranular critical state in high-temperature superconductors. (c) 2005 American Institute of Physics.
