With the objective to collate the enormous amount of information on magnetic susceptibility parameters of a very large number of a variety of skeletons and present it in a form that can readily be retrieved and used, a new pattern is being introduced with the present volume keeping in view that now a majority of research groups look at the scientific data electronically.

In this volume, magnetic properties of Ni, Pd, Pt, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Th, and U complexes are described.
