Core-Level Photoelectron Spectroscopy Study of UTe
Shin-ichi Fujimori, Ikuto Kawasaki, Yukiharu Takeda +4
The valence state of UTe was studied by core-level photoelectron spectroscopy. The main peak position of the U core-level spectrum of UTe coincides with that of UB…
Multiple Superconducting Phases and Unusual Enhancement of the Upper Critical Field in UTe2
Dai Aoki, Fuminori Honda, Georg Knebel +8
We performed AC calorimetry and magnetoresistance measurements under pressure for H || a-axis (easy-magnetization axis) in the novel heavy-fermion superconductor UTe2. Thanks to th…
Spin-Triplet Superconductivity in UTe2 and Ferromagnetic Superconductors
Dai Aoki, Ai Nakamura, Fuminori Honda +13
The spin-triplet state is most likely realized in uranium ferromagnetic superconductors, UGe2, URhGe, UCoGe. The microscopic coexistence of ferromagnetism and superconductivity mea…
Orientation of point nodes and nonunitary triplet pairing tuned by the easy-axis magnetization in UTe2
Shunichiro Kittaka, Yusei Shimizu, Toshiro Sakakibara +6
The gap structure of a novel uranium-based superconductor UTe, situated in the vicinity of ferromagnetic quantum criticality, has been investigated via specific-heat …
