μSR investigation of a cluster of monodisperse Pd nanoparticles

We report the first μSR measurements done on a cluster of monodisperse Pd nanoparticles. The measurements give access to the dipole field from the unpaired electron magnetic moments. We find for a two shell compound that the field is smaller than expected. The moments at the origin of the field are...

Description
Summary:We report the first μSR measurements done on a cluster of monodisperse Pd nanoparticles. The measurements give access to the dipole field from the unpaired electron magnetic moments. We find for a two shell compound that the field is smaller than expected. The moments at the origin of the field are quasi-static, i.e. fluctuate in the microsecond time range.
