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 …

The novel spin-triplet superconductor candidate UTe 2 was discovered only recently at the
end of 2018 and already attracted enormous attention. We review key experimental and …

The recently discovered superconductor UTe 2, with a superconducting transition
temperature T c between 1.5 and 2 K, is attracting much attention due to strong suspicion of …

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

Our measurements of Te 125 NMR relaxations reveal an enhancement of electronic spin
fluctuations above μ 0 H*∼ 15 T, leading to their divergence in the vicinity of the …

Superconductivity induced by a magnetic field near metamagnetism is a striking
manifestation of magnetically-mediated superconducting pairing. After being observed in …

We present magnetoresistivity measurements on the heavy-fermion superconductor UTe2 in
pulsed magnetic fields μ0 H up to 68 T and temperatures T from 1.4 to 80 K. Magnetic fields …

In this study, the metamagnetic transitions in the novel spin-triplet superconductor UTe2 are
investigated based on the recently developed simultaneous measurements of magnetization …

Geometrical frustration describes situations where interactions are incompatible with the
lattice geometry and stabilizes exotic phases such as spin liquids. Whether geometrical …

Experimental and theoretical investigations on itinerant ferromagnetic systems under
pressure have shown that ferromagnetic quantum criticality is avoided either by a change of …
