Wide glass-forming range in Zr-M alloys (M = late transition metal) combined with a
simple, often linear, variation of their physical properties with composition makes it
possible to deduce physical properties of pure amorphous zirconium. We explore this
possibility by using our experimental results for the magnetic susceptibility and
superconducting transition temperature of paramagnetic amorphous Zr – (Co,Ni,Cu) alloys
extending over a wide composition range. By combining these results with the literature
results for the low temperature specific heat of the same alloy systems, we obtained a set
of parameters associated with the electronic structure of the amorphous Zr. The comparison
of these parameters with the results of the electronic structure calculations for
different crystalline phases of Zr and with the results of the atomic structure and
initial crystallisation studies of the same alloy systems indicate a fcc-like local atomic
structure for amorphous Zr.
