Sources of error in a Faraday magnetometer for magnetic microstructure analysis

摘要

In this work we examine a Faraday magnetometer built for microstructure analysis. We single out sources of error and quantitatively evaluate their effect on the measurement process. From this we derive a generalised estimation concerning temporal, spatial and amplitude resolution. We point out where the examined setup can be improved, but also where the limits of feasibility of a Faraday magnetometer as a means of measuring magnetic microstructures lie.
