How is spin measured experimentally ?

Hi,

this probably has been answered somewhere here already, but I was unable to find it.
Could someone explain how the spin of a particle is actually measured in an experiment ? Most interesting to me is how the 3d spin vector for 1/2 spin particles is determined experimentally.

Cheers.

It is impossible to measure a 3d spin vector - i.e. all three components - of anything.

thank you. the Stern-Gerlach Experiment was helpful indeed.
