【Abstract】 Several frequently\|used ways of data analysis in magnetic penetration depth λ measurements of superconductors are discussed. For experiments where only relative values of Δ λ=λ(T)-λ(0) can be measured, such as microwave surface impedance measurements, etc, care should be taken in fitting the theoretical model to the experimental data to obtain the absolute values of λ(T) . We propose a workable method of data analysis in such a situation.更多还原
