Magnetic Resonance in the Spin-Peierls compound ${\alpha }^{\prime }-Na{V}_2{O}_5$

Abstract

We present results from magnetic resonance measurements for 75-350 GHz in $\alpha$'-NaV${}_2$O${}_5$. The temperature dependence of the integrated intensity indicates that we observe transitions in the excited state. A quantitative description gives resonances in the triplet state at high symmetry points of the excitation spectrum of this Spin-Peierls compound. This energy has the same temperature dependence as the Spin-Peierls gap. Similarities and differences with the other inorganic compound CuGeO${}_3$ are discussed.
