Spin exchange dominated by charge fluctuations of the Wigner lattice in the newly synthesized chain cuprate Na5Cu3O6
N. Zafar Ali, J. Sirker, J. Nuss +2
Na5Cu3O6, a new member of one dimensional charge ordered chain cuprates, was synthesized via the azide/nitrate route by reacting NaN3, NaNO3 and CuO. According to single crystal X-…
Interplay between localized and itinerant d electrons in a frustrated metallic antiferromagnet, 2H-AgNiO2
A. I. Coldea, A. Carrington, R. Coldea +11
We report the electronic and magnetic behaviour of the frustrated triangular metallic antiferromagnet 2H-AgNiO2 in high magnetic fields (54 T) using thermodynamic and transport mea…
Phase transition of the nucleon-antinucleon plasma at different ratios
A. Delfino, M. Jansen, V. S. Timóteo
We investigate phase transitions for the Walecka model at very high temperatures. As is well known, depending on the parametrization of this model and for the particular case of a…
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…
Anomalous temperature evolution of the internal magnetic field distribution in the charge-ordered triangular antiferromagnet AgNiO2
T. Lancaster, S. J. Blundell, P. J. Baker +6
Zero-field muon-spin relaxation measurements of the frustrated triangular quantum magnet AgNiO2 are consistent with a model of charge disproportionation that has been advanced to e…
Spin-1/2 Triangular Lattice with Orbital Degeneracy in a Metallic Oxide Ag2NiO2
H. Yoshida, Y. Muraoka, T. Soergel +2
A novel metallic and magnetic transition metal oxide Ag2NiO2 is studied by means of resistivity, magnetic susceptibility, specific heat and X-ray diffraction. The crystal structure…
