Abstract
We have developed a new technique to study superfluidity in saturated liquid- films. Using the enhanced sensitivity of this new method, we directly observe the suppression of the film's transition temperature as the film thickness decreases. We also measure a well-defined maximum critical film current which scales with temperature as , where .
