Abstract We have studied the superfluid response of {sup 3}He- {sup 4}He mixture films adsorbed onto porous gold for a wide range of {sup 3}He and {sup 4}He coverages, focusing on submonolayer superfluidity. At T=0 , {sup 3}He appears to float on top of {sup 4}He and can be viewed as a second substrate that induces its own inert layer. Depending on the {sup 4}He content, the zero-temperature superfluid mass and the superfluid onset temperature either saturate or vanish with the addition of {sup 3}He . The T=0 superfluid-insulator phase boundary, which can be described by a simple function, is found in the {sup 3}He- {sup 4}He coverage plane.
