The frequency dependence of the surface impedance of different kinds of high-purity copper was measured in the audio frequency region and at low temperatures. The impedance of a coil with and without a rod-shaped sample was measured as a function of frequency. From these values, the surface impedance for copper of different purities was calculated. It was found that the real part of the difference in the coil impedance is proportional to ω^n, where ω is the angular frequency and n ranges from 1/2 (normal skin effect) to 2/3 (anomalous skin effect). This finding suggests that the surface impedance of high-purity copper at low temperatures can be better explained interms of the anomalous skin effect than the normal skin effect.
