Hole Doping Effects on Spin-gapped Na2Cu2TeO6 via Topochemical Na Deficiency

K. Morimoto, Y. Itoh, K. Yoshimura +2

We report the magnetic susceptibility and NMR studies of a spin-gapped layered compound Na2Cu2TeO6 (the spin gap $\Delta \sim$ 250 K), the hole doping effect on the Cu2TeO6 plane via a t…
