| Abstract: | Low temperature a.c. conductivity of β-alumina is of the form σ(ω) = σ(ω) + Aωn. Both σ(0) and A are found to be thermally activated. Simple relationships, dependent on the value of n, are shown to exist between (i) the relative magnitudes of σ(0) and A and (ii) their respective activation energies. |
