In a previous volume, VIII/11A, the same author analyzed the hard magnetic nanomaterials based on rare earth–transition metal compounds. As an on- going work, the present volume focuses on the physical properties of the transition metal hard magnetic nanophases. These materials are of interest for high density information storage devices. Thus, in the first section, the author reviews the physical properties of disordered Co Pt hard magnetic solutions, 100–x x whereas in the second one, those of ordered hexagonal Co Pt phase. The last section is devoted to the 3 CoPt, CoPd, FePt, and FePd compounds. The quasi-entire compositional ranges of the phase diagrams of the above systems are covered. The elaboration of hard magnetic nanomaterials as well as their physical properties including crystal structures, mechanical, magnetic, thermodynamic, optical and magneto-optical properties are presented. The author of the volume is one of those scientists who contribute significantly to the development of the field of nanostructured hard magnetic materials. This is clearly visible throughout the volume, where representative data are included and critically analyzed. The volume provides a state-of-the-art knowledge base and a valuable analysis of the up-to-date results based on an extended reference list. The possible directions of research for the development of the field are also indicated. Taking the above into account, the volume is recommended for all those involved in the research area of nanostructured hard magnetic materials as well as in their technical applications. I would like to thank Antje Endemann from the Landolt-Börnstein editorial office for the agreeable cooperation and help with all the editorial work. Also, I express my gratitude to the Springer Verlag for providing all the necessary steps for the completion of this volume.
