ABSTRACT: The
spin-magnetic moment of the electron is revisited. In the form of the
relativistic quantum mechanics, we calculate the magnetic moment of Dirac
electron with no orbital angular-momentum. It is inferred that obtained
magnetic moment may be the spin-magnetic moment, because it is never due to
orbital motion. A transition current flowing from a positive energy state to a
negative energy state in Dirac Sea is found. Application to the band structure
of semiconductor is suggested.
