This book brings together an emerging consensus on our understanding of the complex functional materials including ferroics, perovskites, multiferroics, CMR and high-temperature superconductors. The common theme is the existence of many competing ground states and frustration as a collusion of spin, charge, orbital and lattice degrees of freedom in the presence of disorder and (both dipolar and elastic) long-range forces. An important consequence of the complex unit cell and the competing interactions is that the emergent materials properties are very sensitive to external fields thus rendering these materials with highly desirable, technologically important applications enabled by cross-response.

Prof. Kakeshita is a leading researcher in the discipline of physical properties under extreme conditions. He also is the leader of a Global COE program, which is competitive educational program for PhD course student supported by the Japanese government.Dr. Fukuda is a distinguished researcher in the field of martensitic transformation.Prof. Planes and Dr. Saxena have previously been co-editors of a Springer book on "Magnetism and Structure in Functional Materials".
