Abstract

Frequency dependence of the AC loss in MgB₂ is analyzed using the eddy current model. Utilizing equations for temperature dependent penetration depth and electrical resistance, a fitting function for χ"(T) which is proportional to i(T)/B_ac is obtained. The comparison of the χ"(T) measurements with the corresponding fit described by the eddy current model show satisfactory agreements. The frequency dependence of the penetration depth and the electrical resistance were deduced.
