摘要：

Measurements of the complex ac conductivity are reported for a single crystal of La2CuO4 for frequencies 10(2) less-than-or-equal-to v less-than-or-equal-to 10(9) Hz and temperatures 25 less-than-or-equal-to T less-than-or-equal-to 300 K. The conductivity follows a power-law behavior omega(s) with the frequency exponent s independent of temperature and independent of frequency. However, the hopping transport is strongly anisotropic, with s almost-equal-to 0.75 within the CuO2 planes and s almost-equal-to 0.25 perpendicular to the planes.
