An overview of quantum phase transitions (QPTs) in metallic ferromagnets, discussing both
experimental and theoretical aspects, is given. These QPTs can be classified with respect to …

Strongly correlated electron systems at the border of magnetism are of active current
interest, particularly because the accompanying quantum criticality provides a route towards …

Unconventional superconductivity and other previously unknown phases of matter exist in
the vicinity of a quantum critical point (QCP): a continuous phase change of matter at …

We describe the design, construction, calibration, and two different applications of a
miniature capacitance dilatometer. The device is suitable for thermal expansion and …

Heavy fermion compounds exhibiting a ferromagnetic quantum critical point have attracted
considerable interest. Common to two known cases, ie, CeRh 6 Ge 4 and YbNi 4 P 2, is that …

We propose the notion of a spin-selective Kondo insulator, which provides a fundamental
mechanism to describe the ferromagnetic phase of the Kondo lattice model with …

The Kondo model predicts that both the valence at low temperatures and its temperature
dependence scale with the characteristic energy TK of the Kondo interaction. Here, we study …

Cerium 4 f electronic spin dynamics in single crystals of the heavy-fermion system CeFePO
is studied by means of ac susceptibility, specific heat, and muon-spin relaxation (μ SR) …

Dimensionality plays an essential role in determining the anomalous non-Fermi liquid
properties in heavy fermion systems. So far most heavy fermion compounds are quasi-two …

We show that Ce-and Yb-based Kondo-lattice ferromagnets order mainly along the
magnetically hard direction of the ground-state Kramers doublet determined by crystalline …
