  Recently, we have shown the existence of a finite energy one-half monopole.
In this paper, we would like to introduce electric charge into the one-half
monopole configuration, thus creating a one-half dyon. This one-half dyon
possesses finite energy, magnetic dipole moment and angular momentum. Hence it
is able to rotate in the presence of an external magnetic field. Similar to the
single pole dyons and the MAP dyons, this one-half dyon possesses critical
(maximum) electric charge, total energy, and magnetic dipole moment when the
Higgs self-coupling constant is nonvanishing, and the electric charge parameter
approaches one. This one-half dyon solution does not satisfy the first order
Bogomol'nyi equations and is a non-BPS solution in the limit of vanishing Higgs
self-coupling constant.
