Questions associated with the magnetic susceptibility of the $d$-band transition metals that are not magnetically ordered, i.e., that are neither ferromagnets nor antiferromagnets, are reviewed. The principal components of the magnetic susceptibility of the transition metals are discussed, theoretical estimates of these components and of the total paramagnetic susceptibility are presented for individual metals, the experimental results on the susceptibility of the transition metals and on the temperature dependence are collected, and methods used to resolve the susceptibility into its individual components are described. The results of studies of the susceptibility of single crystals with the hep structure are analyzed. The experimental results are compared with theoretical estimates.
