  The activation energy (E_A) spectra of potential energy landscape (PEL)
provides a convenient perspective for interpreting complex phenomena in
amorphous materials; however, the link between the E_A spectra and other
physical properties in metallic glasses is still mysterious. By systematically
probing the E_A spectra for numerous metallic glass samples with distinct local
geometric ordering, which correspond to broad processing histories, it is found
that the shear modulus of the samples are strongly correlated with the
arithmetic mean of the E_A spectra rather than with the local geometrical
ordering. Furthermore, we studied the correlation of the obtained E_A spectra
and various well-established physical parameters. The outcome of our research
clearly demonstrates that the soft mode parameter {\Psi} and the E_A spectrum
are correlated; therefore, it could be a good indicator of metallic glass
properties and sheds important light on the structure-property relationship in
metallic glass through the medium of PEL.
