Topological Semimetal KAlGe with Novel Electronic Instability
Toshiya Ikenobe, Takahiro Yamada, Jun-ichi Yamaura +6
Compounds with the anti-PbFCl structure exhibit a variety of electronic instabilities and intriguing physical properties. NaAlSi and NaAlGe are similar topological nodal-line semim…
Structural and Electronic Properties of a Triangular Lattice Magnet NaPrTe Compared with NaNdTe and NaTbTe
Koki Eto, Yoshihiko Okamoto, Naoyuki Katayama +3
NaPrTe2, NaNdTe2, and NaTbTe2 are found to be triangular lattice magnets with the alpha-NaFeO2 structure, where lanthanoid atoms with 4f electrons form a triangular lattice, based…
Superconductivity in Ternary Scandium Telluride Sc6MTe2 with 3d, 4d, and 5d Transition Metals
Yusaku Shinoda, Yoshihiko Okamoto, Youichi Yamakawa +3
We report the discovery of bulk superconductivity in Sc6MTe2 with seven kinds of transition-metal elements M. The critical temperatures for M = 3d elements are higher than those fo…
Inelastic Neutron Scattering Study of the Spin Dynamics in the Breathing Pyrochlore System LiGa0.95In0.05Cr4O8
Yu Tanaka, Rafał Wawrzyńczak, Manh Duc Le +6
The A-site ordered chromate spinels LiGa1-xInxCr4O8 host a network of size-alternating spin-3/2 Cr3+ tetrahedra known as a 'breathing' pyrochlore lattice. For the x=0.05 compositio…
Signatures of a magnetic superstructure phase induced by ultrahigh magnetic fields in a breathing pyrochlore antiferromagnet
M. Gen, A. Ikeda, K. Aoyama +11
The mutual coupling of spin and lattice degrees of freedom is ubiquitous in magnetic materials and potentially creates exotic magnetic states in response to the external magnetic f…
Large Magnetic-Field-Induced Strains in Sintered Chromium Tellurides
Yuki Kubota, Yoshihiko Okamoto, Tomoya Kanematsu +3
Sintered samples of Cr3Te4 and Cr2Te3 are found to show large strains accompanied by large volume changes under a magnetic field. In Cr3Te4, volume increases of deltaV/V = 500-1170…
