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 Tc, the (InR vs 1/T) curves showed a sharp change in the slope at magnetic-field-dependent temperatures T*(H). The T* vs H curves are consistent with vortex-lattice melting, mainly due to quantum fluctuations.
