'Conventional'superconductivity, as used in this review, refers to electron–phonon-coupled
superconducting electron pairs described by BCS theory. Unconventional superconductivity …

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 …

This review discusses instabilities of the Fermi-liquid state of conduction electrons in metals
with particular emphasis on magnetic quantum critical points. Both existing theoretical …

Intermetallic compounds containing f-electron elements display a wealth of superconducting
phases, which are prime candidates for unconventional pairing with complex order …

We report the coexistence of ferromagnetic order and superconductivity in UCoGe at
ambient pressure. Magnetization measurements show that UCoGe is a weak ferromagnet …

The discovery in 2000 that the ferromagnetic (FM) compound UGe2 (T Curie= 52 K at
ambient pressure) becomes superconducting under a pressure of P= 1.1 GPa until it enters …

This review discusses a paradigm that has become of increasing importance in the theory of
quantum phase transitions, namely, the coupling of the order-parameter fluctuations to other …

Recent advances on ferromagnetic superconductors, UGe 2, URhGe and UCoGe are
presented. The superconductivity (SC) peacefully coexists with the ferromagnetism (FM) …

We report a study of the ferromagnetism of Z r Z n 2, the most promising material to exhibit
ferromagnetic quantum criticality, at low temperatures T as a function of pressure p. We find …

Precise resistivity measurements on the ferromagnetic superconductor UGe 2 under
pressure p and magnetic field H reveal a previously unobserved change of the anomaly at …
