The characterisation by "Zr NMR at room temperature is reported for Zr metal (hexagonal close-packed), ZrH2 (tetragonal), ZrC (cubic), ZrCo (cubic), ZQ (monoclinic), ZrQ (3 mol% Y203, tetragonal) and ZrOz (9.3 mol% MgO). The density of states deduced from the Knight shift for zirconium metal agrees
One of the possible microscopic models of nuclear spin relaxation 1 /T, and of the Knight shift K in YBa$u408 proposed is based on a strong electron-phonon interaction, which forms a carged Bose-liquid of small bipolarons (SB). An explanation of the large value of 63( I/T, ), the absence of the Heb
