  We show that electroplated Re films in multilayers with noble metals such as
Cu, Au, and Pd have an enhanced superconducting critical temperature relative
to previous methods of preparing Re. The dc resistance and magnetic
susceptibility indicate a critical temperature of approximately 6 K. Magnetic
response as a function of field at 1.8 K demonstrates type-II
superconductivity, with an upper critical field on the order of 2.5 T. Critical
current densities greater than 10^7 A/m^2 were measured above liquid-helium
temperature. Low-loss at radio frequency was obtained below the critical
temperature for multilayers deposited onto resonators made with Cu traces on
commercial circuit boards. These electroplated superconducting films can be
integrated into a wide range of standard components for low-temperature
electronics.
