Resum: The field-amplitude Hm and circular frequency ω dependent ac susceptibility, χ=χ'−jχ'', of a hard superconducting cylinder with flux-flow type current-voltage characteristic is calculated. A remarkable feature of the resultant χ(Hm,ω) is that both the maximum χ'', χ''m, and dlgHm(χ''m)/dlgω increase with increasing ω. This behavior is observed in actual Bi-2223/Ag tapes and YBa2Cu3O7−δ-coated conductors. Our result provides a useful tool to study the intergranular critical state in high-temperature superconductors.
