Multicomponent metallic glass films inheriting the superior mechanical properties and wide supercooled liquid regions of their bulk counterparts attract increasing attentions for applications in micro-electro-mechanical systems and nano-devices. In this paper, we systematically investigated the growth of multicomponent metallic glass films synthesized using single-target magnetron sputtering. It was found that the working argon gas pressures (P Ar,) and sputtering power are two key factors governing film growth and composition. At high PAr, the glassy films grow via a columnar mode, leading to rough film surface. At low PAr, the films exhibit a negative growth exponent and a nearly atomically flat surface. At appropriate sputtering power and PAr, the films can completely inherit the composition of alloy targets, which makes it possible to fabricate multicomponent glassy films with controllable composition using single targets. The mechanisms accounting for the growth of the glassy films are discussed in the framework of dynamic scaling theory. The diversely tunable film microstructure and composition are expected to lead metallic glasses towards new functional applications.
