Description

The book on Heavy-Fermion Systems is a part of the Book series "Handbook of Metal Physics", each volume of which is written to facilitate the research of Ph.D. students, faculty and other researchers in a specific area. The Heavy-Fermions (sometimes known as Heavy-Electrons) is a loosely defined collection of intermetallic compounds containing rare-earth (mostly Ce) or actinide (mostly U) elements. These unusual names were given due to the large effective mass (100-1,000 times greater than the mass of a free electron) below a critical temperature. They have a variety of ground states including superconducting, antiferromagnetic, paramagnetic or semiconducting. Some display unusual magnetic properties such as magnetic quantum critical point and metamagnetism. This book is essentially a summary as well as a critical review of the theoretical and experimental work done on Heavy Fermions.

About the editor

Prasanta Misra

I have published 100 research papers on magnetic, electric, optical and hyperfine properties of metals, alloys, crystalline and amorphous semiconductors. 10 students have completed their Ph.D. thesis under my supervision. I have been doing research on Heavy-Fermion Systems since 1982 and published several papers to explain their properties.
