Magnetism and spin

A new twist for magnetic moments

01 Sep 2001

The only property of an electron in free space that can be calculated directly from first principles is its magnetic moment. Now an important step has been taken towards determining the magnetic moments of electrons bound within atoms – which is a much tougher challenge.

First discovered in experiments on ions in the early 1920s, the understanding of magnetic moments pl
