Abstract

The precession of muons implanted in a non-magnetic sample at a distance from a magnetized body has been investigated experimentally. Specifically, the muons were implanted into a silver sheet several millimeters from a magnetized nickel sheet. An exact theoretical expression for the field from a uniformly magnetized body was found to provide an excellent description of the average muon precession as a function of distance between the two samples. This experiment illustrates the possibility of using an easy modification to the standard μ SR experiment to provide a bulk probe of the sample magnetization with the same time dependence as the usual local probe. This may help in the interpretation of certain μ SR experiments as well as controlling for sample perturbation by the muons.
