Cascade of field-induced magnetic transitions in a frustrated antiferromagnetic metal
A. I. Coldea, L. Seabra, A. McCollam +10
Frustrated magnets can exhibit many novel forms of order when exposed to high magnetic fields, however, much less is known about materials where frustration occurs in the presence…
Fermi Surface Reconstruction inside the Hidden Order Phase of URu2Si2 Probed by Thermoelectric Measurements
Alexandre Pourret, Alexandra Palacio-Morales, Steffen Kramer +5
We report thermoelectric measurements of the low carrier heavy fermion compound URu2Si2 at high fields up to 34T and at low temperatures down to 500mK. The field dependence of the…
Landau spectrum and twin boundaries of bismuth in the extreme quantum limit
Zengwei Zhu, Benoit Fauque, Liam Malone +3
The Landau spectrum of bismuth is complex and includes many angle-dependent lines in the extreme quantum limit. The adequacy of single-particle theory to describe this spectrum in…
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…
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…
Pressure Evolution of the Magnetic Field induced Ferromagnetic Fluctuation through the Pseudo-Metamagnetism of CeRu2Si2
Dai Aoki, Carley Paulsen, Tatsuma D. Matsuda +7
Resistivity measurements performed under pressure in the paramagnetic ground state of CeRu2Si2 are reported. They demonstrate that the relative change of effective mass through the…
