High-field moment polarization in the ferromagnetic superconductor UCoGe
W. Knafo, T. D. Matsuda, D. Aoki +7
We report magnetization and magnetoresistivity measurements on the isostructural ferromagnetic superconductors UCoGe and URhGe in magnetic fields up to 60 T and temperatures from 1…
Antiferromagnetic criticality at a heavy-fermion quantum phase transition
W. Knafo, S. Raymond, P. Lejay +1
The interpretation of the magnetic phase diagrams of strongly correlated electron systems remains controversial. In particular, the physics of quantum phase transitions, which occu…
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…
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…
Angular Dependence of the High-Magnetic-Field Phase Diagram of URu2Si2
Gernot W. Scheerer, William Knafo, Dai Aoki +1
We present measurements of the magnetoresistivity RHOxx of URu2Si2 single crystals in high magnetic fields up to 60 T and at temperatures from 1.4 K to 40 K. Different orientations…
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…
