Magnetic properties of almost localized fermions revisited: spin dependent masses and quantum critical behavior
The Editor's Choice  of this issue of physica status solidi (b) discusses spectacular phenomena in correlated electron systems viewed as quantum materials. The cover figure is a schematic representation of the transformation from the Kondo insulator (KI) state to the non-Fermi liquid (NFL) state with short-range antiferromagnetic correlations at the critical concentration, when the Kondo singlet state is destroyed. AFI denotes the antiferromagnetic insulating state.
The author Jozef Spałek heads the Condensed Matter Theory Division in the Institute of Physics of the Jagiellonian University Kraków. His scientific interests include the theory of Mott–Hubbard and heavy-fermion systems, with a particular emphasis on quantum critical behavior close to the electron localization.
This issue contains presentations from The European Conference Physics of Magnetism (PM'05) held in Poznan, Poland, 24–27 June 2005. Further articles from PM'05 can be found in phys. stat. sol. (c) 3, No. 1 (2006).
