  A correlation between the change in magnetic susceptibility
({\Delta}\c{hi}exp) upon crystallization of Cu-Zr, Hf metallic glasses (MG)
with their glass forming ability (GFA) observed recently is found to apply to
Cu-Ti and Zr-Ni alloys, too. In particular, a small {\Delta}\c{hi}exp , which
reflects similar electronic structures, ES, of glassy and corresponding
crystalline alloys, corresponds to high GFA. Here, we studied {\Delta}\c{hi}exp
in five Cu-Ti and four Cu-Zr and Ni-Zr MGs. The fully crystalline final state
of all alloys was verified from X-ray diffraction patterns. The variation of
GFA with composition in Cu-Ti, Cu-Zr and Cu-Hf MGs was established from the
variation of the corresponding critical casting thickness, dc. Due to the
absence of data for dc in Ni-Zr MGs their GFA was described by using empirical
criteria, such as the reduced glass transition temperature. A very good
correlation between {\Delta}\c{hi}exp and dc (and/or other criteria for GFA)
was observed for all alloys studied. The correlation between the ES and GFA
showed up best for Cu-Zr and NiZr2 alloys where direct data for the change in
ES ({\Delta}ES) upon crystallization are available. The applicability of the
{\Delta}\c{hi}exp ({\Delta}ES) criterion for high GFA (which provides a simple
way to select the compositions with high GFA) to other metal-metal MGs
(including ternary and multicomponent bulk MGs) is briefly discussed.
