Abstract
We have measured the electrical resistance R vs temperature T in different perpendicular magnetic fields on Nb/CuMn multilayers. The samples had constant Nb layer thickness (∼230 Å) and CuMn layer thicknesses in the range 4-50 Å. Below the zero-field superconducting critical temperature (Formula presented), the (lnR vs 1/T) curves showed a sharp change in the slope at magnetic-field-dependent temperatures (Formula presented)(H). The (Formula presented) vs H curves are consistent with vortex-lattice melting, mainly due to quantum fluctuations.
