Introduction	Our study indicates that rhenium films developed through electroplating, when layered with noble metals such as copper, gold, and palladium, present an advanced superconducting critical temperature compared to older methods of Re preparation. Measurements of direct current resistance and magnetic susceptibility reveal a critical temperature near 6 K. The magnetic field response at 1.8 K confirms type-II superconductivity with an upper critical field around 2.5 T. We recorded critical current densities exceeding 10^7 A/m^2, even above liquid-helium temperatures. These films exhibit low radio frequency loss when applied to resonators with copper traces on standard circuit boards, making them suitable for integration in various low-temperature electronic components.
