Interaction Of Spin-Polarized Electrons

[Fluxation]

I refer to spin-polarization of electrons by conducting them through a ferromagnetic material such as a permanent magnet.

 

Are there any differences in physical properities or behavior between a lefthand and righthand spun electron?

 

What occur if two oppositely spun electrons were made to converge?

I had never heard of polarised currents before and had some trouble locating any information about them on the web. I did in the end find a PhD thesis written at Stanford on the subject:http://snow.stanford.edu/thesis/Gao.pdf

 

Regarding your question I should think the only difference is the spatial orientation of the magnetic moment.

 

In most matter, electrons of opposite spin direction co-exist in the same region of space. (In any atom other than hydrogen you have paired electrons sharing atomic orbitals.) So I don't think anything special would happen if you make two electrons of opposite spin converge. I suppose they would experience the expected electrostatic repulsion, but that's about it, I should think.
