Superconductivity in the Hexagonal Ternary Phosphide ScIrP
Yoshihiko Okamoto, Takumi Inohara, Youichi Yamakawa +2
We report the discovery of a bulk superconducting transition at 3.4 K in the ternary phosphide, ScIrP, which crystallizes in a hexagonal ZrNiAl-type structure without spatial inver…
Line-Node Dirac Semimetal and Topological Insulating Phase in Noncentrosymmetric Pnictides CaAgX (X = P, As)
Ai Yamakage, Youichi Yamakawa, Yukio Tanaka +1
Two noncentrosymmetric ternary pnictides, CaAgP and CaAgAs, are reported as topological line-node semimetals protected solely by mirror-reflection symmetry. The band gap vanishes o…
One-Third Magnetization Plateau with a Preceding Novel Phase in Volborthite
H. Ishikawa, M. Yoshida, K. Nawa +12
We have synthesized high-quality single crystals of volborthite, a seemingly distorted kagome antiferromagnet, and carried out high-field magnetization measurements up to 74 T and…
Orbital Arrangements and Magnetic Interactions in the Quasi-One-Dimensional Cuprates ACuMoO_4(OH) (A = Na, K)
Kazuhiro Nawa, Takeshi Yajima, Yoshihiko Okamoto +1
A new spin-1/2 quasi-one-dimensional antiferromagnet KCuMoO_4(OH) is prepared by the hydrothermal method. The crystal structures of KCuMoO_4(OH) and the already-known Na-analogue,…
Frozen State and Spin Liquid Physics in Na4Ir3O8: an NMR study
A. C. Shockley, F. Bert, J-C Orain +2
Na4Ir3O8 is a unique case of a hyperkagome 3D corner sharing triangular lattice which can be decorated with quantum spins. It has spurred a lot of theoretical interest as a spin li…
Magnetic Phase Diagram of the Breathing Pyrochlore Antiferromagnet LiGa1-xInxCr4O8
Yoshihiko Okamoto, Gøran J. Nilsen, Taishi Nakazono +1
The spinel oxides LiGaCr4O8 and LiInCr4O8 contain size-alternating pyrochlore lattices of spin-3/2 Cr3+ tetrahedra with different magnitudes of alternation. We show here that the s…
