Experimental evidence for a spin-Peierls-transition in ${\alpha }^{\prime }-Na{V}_2{O}_5$

M. Weiden, R. Hauptmann, C. Geibel +4

We present the first measurements of magnetisation and Raman light scattering on ${\alpha }^{\prime }-Na{V}_2{O}_5$ single crystals. Below 34 K, we observe a pronounced isotropic decrease of the suscep…
