A relatively new class of materials has been found in which the basic assumption of Landau
Fermi-liquid theory—that at low energies the electrons in a metal should behave essentially …

This review discusses the heavy-electron compounds and related materials from the
perspective of their electrodynamic response. The investigation of the electrodynamic …

NATURE abounds with phase transitions. The boiling and freezing of water are everyday
examples of phase transitions, as are more exotic processes such as superconductivity and …

At a generic quantum critical point, the thermal expansion α is more singular than the
specific heat cp. Consequently, the “Grüneisen ratio,” Γ= α/cp, diverges. When scaling …

A crossover with decreasing temperature T from localized moment magnetism to heavy
Fermi liquid behavior is reported for the metallic compound LiV 2 O 4 with the fcc normal …

We study the competition between the Kondo effect and Ruderman-Kittel-Kasuya-Yosida
interactions near the zero-temperature quantum critical point of an Ising-like metallic spin …

We have studied superconducting and magnetic properties of RERu 4 Sb 12 prepared by an
Sb-flux method and found that LaRu 4 Sb 12 is superconducting below 3.58 K and PrRu 4 …

We present a detailed study of the phase diagram of the antiferromagnetic Kondo-lattice
compound CeIn 3 under pressure up to 100 kbar by resistivity measurements …

Ni x Pd 1− x is investigated at the border of enhanced Pauli paramagnetism and itinerant
ferromagnetism. We provide convincing experimental evidence for the occurrence of a …

We have carried out a detailed study of the (Ce 1− x Y x) 2 Ir 3 Ge 5 anti-ferromagnetic
compounds across the entire range of substitution 0≤ x≤ 0.33 and report the results of …
