High-Efficiency and Large Supercurrent Rectification with Superconducting Coil
Takumi Ichikawa, Daisuke Takegami, Gen Nishijima +8
Superconducting diodes (SDs) are devices that rectify supercurrent through the difference in the superconducting critical current (Ic) between forward and reverse current direction…
Charge-Transfer Electronic Structure of NiX (X = S, Se)
Atsushi Hariki, Takaki Okauchi, Daisuke Takegami +8
We investigate the electronic structures of NiS and NiSe using density functional theory combined with dynamical mean-field theory (DFT+DMFT). A realistic electronic struct…
Distinct Roles of Hydrogen in Superconducting and Ferromagnetic Phases of CoZrH
Yuto Watanabe, Takayoshi Katase, Daisuke Takegami +1
Hydrogenation offers a versatile route to tuning the physical properties of intermetallic compounds. In this study, we synthesized CoZrH with different hydrogen content…
Probing La-based nickelates with Ni 1 core-level photoelectron spectroscopy
Daisuke Takegami, Naoki Ito, Koto Fujinuma +15
We present a comparative Ni core level photoemission study of LaNiO, NdNiO, and LaNiO using both the Ni and the Ni . We address the challenges…
UCd: A strongly localized 5 material
Martin Sundermann, Naoki Ito, Daisuke Takegami +11
UCd is an antiferromagnetic uranium intermetallic compound ( = 5.3K) with enhanced electron mass and uranium-uranium spacings nearly twice the Hill limit, suggest…
Liquid-state structural asymmetry governs species-selective crystallization in multicomponent systems
Rikuya Ishikawa, Kyohei Takae, Daisuke Takegami +2
Multicomponent crystals are often assumed to form nearly random solid solutions when thermodynamically stable. However, crystal growth proceeds from structurally heterogeneous liqu…
