Properties and atomic structure of amorphous early transition metals

Recently, we studied the properties of amorphous Zr-TL alloys (TL = Ni, Cu) in order to obtain parameters associated with the electronic structure and interatomic bonding of amorphous Zr. Here, we provide new data for the magnetic, superconducting and mechanical properties of amorphous Hf-TL and Ti-TL alloys. We combine our results with published data in order to obtain parameters appropriate to hypothetical amorphous Hf and Ti. These parameters are very different from those of the stable crystalline phases (hcp) of Hf and Ti and indicate, as for Zr, an fcc-like short range order for amorphous Hf and Ti. This results in an enhanced electronic density of states at the Fermi level, but in weakened interatomic bonding.
