      abstract     = {Contrary to basic hard sphere structure models, recent
                      studies revealed, significant structural differences between
                      Pt-Cu-Ni-P and Pd-Cu-Ni-P metallic glass-forming liquids
                      with the same stoichiometry. To cover the compositional
                      space between both systems, Platinum is subsequently
                      replaced by Palladium in the composition
                      (Pt/Pd)$_{42.5}$Cu$_{27}$Ni$_{9.5}$P$_{21}$. For this
                      systematic set of alloys, the thermodynamic properties, such
                      as isobaric heat capacity, enthalpy and Gibbs free energy
                      are assessed. A systematic drop of the Gibbs free energy
                      difference between crystal and liquid, providing a lower
                      estimate of the driving force for crystallization was
                      observed, underlining the high glass-forming ability of the
                      Pd-rich systems. Contrary to kinetic fragility data, a
                      change of the thermodynamic fragility can be observed,
                      drawing the picture of an increasing thermodynamically
                      strong behavior with rising Pd-content. Further the
                      temperature induced changes of the total structure factors
                      S(Q) were monitored using high-energy synchrotron X-ray
                      diffraction. Focus was laid on the changes on the
                      medium-range length scale, by analyzing changes of the first
                      sharp diffraction peak. Here a good correlation of the
                      changes in peak-width and the thermodynamic fragility was
                      found. From the determination of the excess enthalpy, large
                      amounts of residual enthalpy in the glassy state were
                      observed for the Pt-rich alloys, supporting the increased
                      ductility of these alloys. The current findings further
                      carve out the different roles of the topologically similar
                      Pt and Pd in the Pt/Pd-Cu-Ni-P alloy system and how the
                      change of the structural motifs on the medium range order is
                      structurally influencing thermal properties such as enthalpy
                      and heat capacity.},
