Superconductivity at 12 K in LaIOs: a 5d metal with osmium honeycomb layer
Hajime Ishikawa, Takeshi Yajima, Daisuke Nishio-Hamane +3
We discovered superconductivity at = 12 K in a layered compound LaIOs with osmium honeycomb network. Despite heavy constituent elements unfavorable for phonon mediate…
Spin-Peierls transition to a Haldane phase
Hironori Yamaguchi, Hiroki Takahashi, Takashi Kawakami +4
We present an organic compound exhibiting a spin-Peierls (SP) transition to an effective spin-1 antiferromagnetic uniform chain, that is, the Haldane chain. The clear disappearance…
Breathing pyrochlore magnet CuGaCrS: Magnetic, thermodynamic, and dielectric properties
M. Gen, H. Ishikawa, A. Miyake +11
We investigate the crystallographic and magnetic properties of a chromium-based thiospinel CuGaCrS. From a synchrotron x-ray diffraction experiment and structural refin…
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…
