Hall effect and electronic structure of glassy Zr 3d alloys

Accurate Hall coefficients of glassy Zr 1-x Fe x , Zr 1-x Co x , Zr 1-x Ni x and Zr 1-x Cu x alloys are reported. In Zr-rich alloys the Hall coefficient is positive and changes sign (except for ZrFe alloys) at progressively higher concentrations (x) in going from ZrCo to ZrCu alloys. A correlation is found between the cross-over concentration and the concentration at which the nature of the states at the Fermi level changes from being predominantly of Zr d character to being predominantly of solute d character.
