NMR study of the magnetic and metal-insulator transitions in Na0.5CoO2: a nesting scenario

J. Bobroff, G. Lang, H. Alloul +2

Co and Na NMR are used to probe the local susceptibility and charge state of the two Co sites of the Na-ordered orthorhombic Na0.5CoO2. Above T_N=86K, both sites display a similar…
