Hardcover Abstract: The data compiled refer to susceptibility measurements (susceptibility, Curie-constants, magnetic moments, transition temperatures) and ESR-measurements (g-factors and other parameters of the applied spin Hamiltonian). In volume II/2 the literature from 1899 up to 1964 has been considered. Volume II/8 supplements volume II/2, taking into account the data on magnetic susceptibilities and ESR parameters published in the p eriod 1964 to 1968. The following subvolumes II/10,II/11, II/12 supplement data up to 1974.
