Coherence-driven origin of metamagnetism in anisotropic heavy-fermion systems
Ewan Scott, Zheyu Wu, Theodore I. Weinberger +2
A number of heavy-fermion materials exhibit magnetic field-induced metamagnetism: on applying a field along the magnetic hard axis, the magnetization first rises gradually, then ju…
Metamagnetism in UTe2: the roles of itinerancy and localization
Theodore I. Weinberger, Daniel Shaffer, Zheyu Wu +12
The metamagnetic transition in UTe plays a key role in stabilizing two enigmatic field-induced superconducting phases. One of these phases (SC2) is truncated by the transition,…
Kondo singlet from ferromagnetic coupling: an analog of Anderson-Morel superconductivity in the magnetic channel
Ewan Scott, Yaqi Chen, Michael Turaev +4
We consider magnetic impurities coupled to a conduction sea via a fully isotropic ferromagnetic spin-exchange term, the strength of which depends on the conduction-electron modes i…
Microscopic origin of hard-plane antiferromagnetism in the Kondo lattice Ce2Rh3Ge5
Rajesh Tripathi, Ewan Scott, D. T. Adroja +16
Hard plane antiferromagnetic order where ordered moments lie perpendicular to the single-ion crystal electric field easy axis is rare in Ce-based Kondo lattices and is a subject of…
Inverted anisotropy of the partially screened magnetic impurity
Krzysztof P. Wójcik, MichaŠP. Kwasigroch
We investigate a single magnetic impurity in the presence of strong spin-orbit coupling and single-ion anisotropy. We show that at sufficiently strong coupling there exists a finit…
Destabilisation of local magnetic anisotropy in heavy-fermion compounds
Ewan Scott, Michal Kwasigroch
The local magnetic anisotropy of a typical crystalline compound is usually attributed to the combined effect of crystal electric fields and spin-orbit coupling. We show that this s…
