Spin excitations in the antiferromagnet NaNiO2
Sophie De Brion, C. Darie, M. Hopzapfel +5
In NaNiO2, Ni3+ ions form a quasi two dimensional triangular lattice of S = 1=2 spins. The magnetic order observed below 20K has been described as an A type antiferromagnet with fe…

Decoupling of orbital and spin degrees of freedom in Li1-xNaxNiO2
M. Hopzapfel, S. Debrion, C. Darie +6
In the Li1-xNaxNiO2 solid solutions three different single phase regions exist: for x > 0.9, forx = 0.7 and for x < 0.3. Although the intermediate compound does not show the cooper…
