Abstract

The power-law E (J) characteristic of a superconductor may be determined by ac susceptibility (= ′ -j ″) measurements from the field amplitude at which ″ takes maximum, Hm (m″), and frequency f. The relation between E vs J and Hm (m″) vs f obtained from direct calculations of for a long cylinder and a thin disk with a power-law E (J) provides a firm base for the ac susceptibility technique of Jc determination of advanced high-temperature superconductors. © 2006 American Institute of Physics.
