Spin-1/2 kagome compounds: volborthite vs herbertsmithite
Z Hiroi, H Yoshida, Y Okamoto +1
Two kagome compounds, volborthite Cu3V2O7(OH)2-2H2O and herbertsmithite ZnCu3(OH)6Cl2, are compared in order to derive information about the intrinsic properties of the spin-1/2 ka…
Band Jahn-Teller Instability and Formation of Valence Bond Solid in a Mixed-Valent Spinel Oxide LiRh2O4
Yoshihiko Okamoto, Seiji Niitaka, Masaya Uchida +7
We have synthesized a new spinel oxide LiRh2O4 with a mixed-valent configuration of Rh3+ and Rh4+. At room temperature it is a paramagnetic metal, but on cooling, a metal-insulator…
Unique Phase Transition on Spin-2 Triangular Lattice of Ag2MnO2
Hiroyuki Yoshida, Sascha Ahlert, Martin Jansen +3
Ag2MnO2 is studied as a possible candidate compound for an antiferromagnetic XY spin model on a triangular lattice. In spite of the large Curie-Weiss temperature of -430 K found in…
