THEORY, EXPERIMENTS AND COMPUTER SIMULATIONS STUDIES ON INTERMETALLIC COMPOUNDS Part Ⅰ: TRANSPORT PROPERTIES AND TEMPERATURE DEPENDENCE OF RE-Al_2 AND M-Co_2 COMPOUNDS

摘要

The temperature dependence of the transport coefficients for magnetic and non-magnetic compounds from the series RE-Al_2, M-Co_2 and RE-Cu_4-M is investigated. Measuring methods and their application in the study of some interesting phenomena (e.g. Kondo-effect, crystal field splitting, spin fluctuations) are presented. The scattering processes determining the thermal and electrical resistive behaviour are discussed and correlated with theoretical models. Phenomena interpretation, fitting procedures and computer simulations are performed in order to obtain qualitative and quantitative information on the intrinsic properties of materials in solid state.
