Ferroics and Multiferroics
Description:
Multiferroics: that is, materials which simultaneously exhibit both ferromagnetism and ferroelectricity - and also often ferroelasticity - now attract considerable attention because of the interesting physics involved and their promise for important practical applications. Typical multiferroics belong to the perovskite group of transition metal oxides, and include rare-earth manganites and ferrites. Several new multiferroic systems have been developed, during recent years, which exhibit very strong coupling between the ferroelectric and magnetic degrees of freedom. The present volume comprises both review articles, and research papers on various themes; with very little overlap. The authors of the review papers have generally kept in mind the unfamiliarity, of the field of ‘Ferroics and Multiferroics’, to newcomers. They cover the historical development of the field, and add their own contributions.

Review from Ringgold Inc., ProtoView:
Multiferroics<-->which simultaneously display ferromagnetism and ferroelectricity and often ferroplasticity<-->are attracting considerable attention because of the interesting physics involved and the promise of important practical applications. Balancing theory and experiment, 12 invited, peer-reviewed papers explore the materials from such perspectives as combing magnetism and ferroelectricity towards multiferroicity, intrinsic free electrons/holes at polarization discontinuities and their implications for the basics of ferroelectricity and its origin, molecular spintronics, recent applications of Landau-Ginzburg theory to ferroelectric superlattices, ferromagnetic shape memory Heusler alloys, and dielectric relaxation phenomena in some lead and non-lead based ferroelectric relaxor materials.
