Novel Pauli-paramagnetic quantum phase in a Mott insulator
D. Watanabe, M. Yamashita, S. Tonegawa +9
In Mott insulators, the strong electron-electron Coulomb repulsion prevents metallicity and charge excitations are gapped. In dimensions greater than one, their spins are usually o…
Incomplete devil's staircase in the magnetization curve of SrCu2(BO3)2
Masashi Takigawa, Mladen Horvatić, Takeshi Waki +7
We report on NMR and torque measurements on the frustrated quasi-two-dimensional spin-dimer system SrCu2(BO3)2 in magnetic fields up to 34 T that reveal a sequence of magnetization…
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…
Heavy fermions in high magnetic field
D. Aoki, W. Knafo, I. Sheikin
We give an overview on experimental studies performed in the last 25 years on heavy-fermion systems in high magnetic field. The properties of field-induced magnetic transitions in…
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…
