I'm aware of the Stern Gerlach classic experiment to measure electron
spin ( or mag moment) but was there another that used electric fields
instead of magnetic fields to measure spin along a designated axis??
I have tried searching for this without any luck. Thanks jk |

There have been numerous measurements of the electron's anomalous
magnetic moment. Google "electron g-2" finds lots of information (the
experiments are sensitive to g-2, not to g itself; 2 is the
semi-classical value). There have also been measurements of the muon's
anomalous magnetic moment.

An electron's spin is not sensitive to the electric field. So, any
experiments trying to measure the magnitude of the spin or any other
of its properties would have to primarily involve magnetic fields. If
you replace "electric field" by "magnetic field" in your question,
then it sounds like you have precisely the Stern-Gerlach experiment in
mind.
