在0.03K以下的低温下测量了各种石墨晶体的电导率和磁导率。在多晶（但取向良好）石墨样品中发现了异常行为。在低于0.1K的低温下，在有磁场和无磁场的情况下，电导率都表现出T1/2依赖性，并观察到各向异性的磁导。它随H 1/2变化，随着磁场强度的增加，其符号从负变为正。这些行为是相当好的解释方面的本地化和电子-电子相互作用的三维弱本地化制度。非弹性散射时间τ e的温度依赖性比T-1弱。
Conductivity and magnetoconductivity have been measured for various kinds of graphite crystals at low temperatures down to 0.03 K. Anomalous behaviours have been found in polycrystalline (but well oriented) specimens of graphite. At low temperatures below 0.1 K, the conductivity shows T 1/2 dependence in and without magnetic field, Anisotropic magnetoconductivity is observed. It varies as H 1/2 , with the sign which changes from negative to positive with increasing magnetic field strength. These behaviors are fairly well explained in terms of localization and electron-electron interaction in the three-dimensional weakly localized regime. The inelastic scattering time τ e shows a little weaker temperature dependence than T -1 .
