Superconductivity in an Einstein Solid AxV2Al20 (A = Al and Ga)
Atsushi Onosaka, Yoshihiko Okamoto, Jun-ichi Yamaura +1
A cage compound AxV2Al20 (Al10V), that was called an Einstein solid by Caplin and coworkers 40 years ago, is revisited to investigate the low-energy, local vibrations of the A atom…
Tuning the spin dynamics of kagome systems
D. Wulferding, P. Lemmens, H. Yoshida +2
Despite the conceptional importance of realizing spin liquids in solid states only few compounds are known. On the other side the effect of lattice distortions and anisotropies on…
High-field Phase Diagram and Spin Structure of Volborthite Cu3V2O7(OH)2/2H2O
Makoto Yoshida, Masashi Takigawa, Steffen Kramer +6
We report results of 51V NMR experiments on a high-quality powder sample of volborthite Cu3V2O7(OH)2/2H2O, a spin-1/2 Heisenberg antiferromagnet on a distorted kagome lattice. Foll…
Superconductivity and Rattling under High Pressure in the beta-Pyrochlore Oxide RbOs2O6
Nao Takeshita, Hiroki Ogusu, Jun-ichi Yamaura +2
Rattling-induced superconductivity in the beta-pyrochlore oxide RbOs2O6 is investigated under high pressures up to 6 GPa. Resistivity measurements in a high-quality single crystal…
A Magnetic Transition Probed by the Ce Ion in Square-Lattice Antiferromagnet CeMnAsO
Yuto Tsukamoto, Yoshihiko Okamoto, Kazuyuki Matsuhira +2
We examined the magnetic properties of the square-lattice antiferromagnets CeMnAsO and LaMnAsO and their solid solutions La1-xCexMnAsO by resistivity, magnetic susceptibility, and…
Magnetization Plateaus in the Spin-1/2 Kagome Antiferromagnets: Volborthite and Vesignieite
Yoshihiko Okamoto, Masashi Tokunaga, Hiroyuki Yoshida +3
The magnetization of two spin-1/2 kagome antiferromagnets, volborthite and vesignieite, has been measured in pulsed magnetic fields up to 68 T. A magnetization plateau is observed…
