摘要: Abstract Theoretically, it has been shown that spin fluctuation scattering influence the transport phenomena in following way: Electrical resistivity: ϱ = AT2, with tendency to saturate at elevated temperatures, thermal W cT low temperature, followed by maximum of W, magnetoresistance: (Δϱ/ϱ) is negative and proportional square applied field, thermopower: a paramagnon drag effect discussed. The data paramagnetic RCo2 (R Sc, Y Lu) compounds are used verify this fluctuations on experimental data.
