Unconventional Superconductivity in Heavy Fermion UTe2
Dai Aoki, Ai Nakamura, Fuminori Honda +13
We grew single crystals of the recently discovered heavy fermion superconductor UTe2, and measured the resistivity, specific heat and magnetoresistance. Superconductivity (SC) was…
Behavior of the Quantum Critical Point and the Fermi-liquid Domain in the Heavy Fermion Superconductor CeCoIn5 studied by resistivity
Ludovic Howald, Gabriel Seyfarth, Georg Knebel +3
We report detailed very low temperature resistivity measurements on the heavy fermion compounds Ce_{1-x}La_{x}CoIn5 (x=0 and x=0.01), with current applied in two crystallographic d…
Anisotropy of the Upper Critical Field in the Heavy-Fermion Superconductor UTe2 under Pressure
Georg Knebel, Motoi Kimata, Michal Vališka +12
We studied the anisotropy of the superconducting upper critical field in the heavy-fermion superconductor UTe under hydrostatic pressure by magnetoresistivity meas…
Field-induced compensation of magnetic exchange as the possible origin of reentrant superconductivity in UTe
Toni Helm, Motoi Kimata, Kenta Sudo +12
The potential spin-triplet heavy-fermion superconductor UTe exhibits signatures of multiple distinct superconducting phases. For field aligned along the axis, a metamagneti…
Multiband superconductivity in the heavy fermion compound PrOs4Sb12
Gabriel Seyfarth, Jean-Pascal Brison, Marie-Aude Méasson +5
The thermal conductivity of the heavy fermion superconductor PrOs4Sb12 was measured down to Tc/40 throughout the vortex state. At lowest temperatures and for magnetic fields H ~ 0.…
Dimensionality driven enhancement of ferromagnetic superconductivity in URhGe
Daniel Braithwaite, Dai Aoki, Jean-Pascal Brison +4
In most unconventional superconductors, like the high-Tc cuprates, iron pnictides, or heavy fermion systems, superconductivity emerges in the proximity of an electronic instability…
