  The structural, vibrational, and electronic properties of
Ni$_{40}$Pd$_{40}$P$_{20}$ bulk metallic glass have been studied using ${\it
ab\,initio}$ molecular-dynamics simulations and total-energy optimization.
Structural analyses of the resulting ${\it ab\,initio}$ models show the
presence of few to no P-P bonds and two main building blocks, consisting of
tricapped trigonal prism (TTP) and capped square anti-prism (CSAP) with P as
the center of these blocks. The computed Pd and Ni K-edge spectra of extended
x-ray absorption fine structure (EXAFS) are found to be in good agreement with
experimental data. The configurational-average static structure factor and the
generalized vibrational density of states are also observed to be in good
agreement with experimental data.
