Verification of the Wiedemann-Franz law in YbRh2Si2 at a quantum critical point
Y. Machida, K. Tomokuni, K. Izawa +4
The thermal conductivity measurements have been performed on the heavy-fermion compound YbRh2Si2 down to 0.04 K and under magnetic fields through a quantum critical point (QCP) at…
(p,T,H) phase diagram of Heavy Fermion systems : Some systematics and some surprises from ytterbium
D. Braithwaite, A. Fernandez-Pañella, E. Colombier +8
Pressure is the cleanest way to tune heavy fermion systems to a quantum phase transition in order to study the rich physics and competing phases, and the comparison between ytterbi…
High-Field Fermi Surface Properties in the Low Carrier Heavy Fermion Compound URu2Si2
Dai Aoki, Georg Knebel, Ilya Sheikin +4
We performed the Shubnikov-de Haas (SdH) experiments of the low carrier heavy fermion compound URu2Si2 at high fields up to 34T and at low temperatures down to 30mK. All main SdH b…
Thermoelectric response near a quantum critical point of beta-YbAlB4 and YbRh2Si2: A comparative study
Y. Machida, K. Tomokuni, C. Ogura +7
The thermoelectric coefficients have been measured on the Yb-based heavy fermion compounds beta-YbAlB4 and YbRh2Si2 down to a very low temperature. We observe a striking difference…
Field-induced Phenomena in Ferromagnetic Superconductors UCoGe and URhGe
Dai Aoki, Mathieu Taupin, Carley Paulsen +13
We review our recent studies on ferromagnetic superconductors, UGe2, URhGe and UCoGe, where the spin-triplet state with the so-called equal spin pairing is realized. We focus on ex…
Thermoelectricity of the Ferromagnetic Superconductor UCoGe
Liam Malone, Ludovic Howald, Alexandre Pourret +4
UCoGe exhibits superconductivity in the presence of ferromagnetism. When a field is applied along the b axis (perpendicular to the easy axis), ferromagnetism is weakened and superc…
