The immittance spectra (i.e., impedance and modulus representations) are calculated for various effective medium theories, i.e., the Maxwell-Wagner (MW), Hashin-Shtrikman (HS), Bruggeman Asymmetric (BA) and Bruggeman Symmetric (BS) models, with empha

The anomalous decrease in the resistivity observed in the amorphous CrxSi1-x, CrxGe1-x, and FexGe1-x systems as T decreases below about 30 K, and the subsequent increase in the resistivity as the temperature decreases below about 4 K are investigated

The general effective media (GEM) equation is shown to quantitatively describe the complex dielectric constants of a binary mixture of lead magnesium niobate and pyrochlore as a function of the volume fraction, over the entire range of composition, a

It is shown that the temperature dependent magnetoresistance data of a sample in the weak antilocalization regime lies on a single curve of d In R(B, T)/d In B versus In (R(B, T)/R(0, T)). R(B, T) is the resistivity of the sample, B is the applied ma

(Cr1-xMox)75Ru25 alloys with x=0, 3%, 6% or 10% exhibit superconducting properties below 3 K. For low Mo concentrations comparison with theory suggests a coexistence of spin density wave antiferromagnetism and superconductivity while the spin density

The results analyzed, all from previous work, are for W‐Al2O3 (as prepared and annealed; 300 K) and Ni‐SiO2 (4.2 and 291 K). These results, in which the resistivity changes from 10−5 to 107 Ω cm as the metal volume fraction is varied, can all

The effect of varying the carrier concentration and type (electrons and holes, or holes only) on weak-antilocalisation parameters such as the inelastic scattering length is studied. Disordered bismuth-based films are used, and the carrier concentrati
