The results of research on the crystalline-electric-field (CEF) effect in RCu₂, R₂Fe₁₄B and RFe₁₁Ti compounds are presented. In the study of the CEF effect in the RCu₂ compounds, attention is paid to the combined analysis of specific heat and thermal expansion. An attempt has been undertaken to investigate the systematic behavior of CEF interactions by comparing different compounds with the same crystallographic structure. From the analysis of spin-reorientation phenomena in R₂Fe₁₄B and RFe₁₁Ti compounds the sets of CEF parameters are derived. © 2002 Elsevier Science B.V. All rights reserved.
