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…

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…
