Abstract: The magnetic-field distribution in the mixed state of superconducting Nb3Sn powder has been studied by the NMR decoration method. As NMR probe we have used thin silicone oil layers formed around individual grains of the Nb3Sn powder. The thickness of the silicone layer is smaller than the flux-lattice parameter, a necessary condition to study with NMR the intrinsic field inhomogeneity. By measuring the temperature dependence of the additional NMR-line broadening, we were able to determine the penetration depth lambda and its temperature dependence.
