  In this letter, we point out that possible sources of CP violation originate
from radiative corrections to soft terms which are ubiquitous in supergravity
theories and also in other high-energy frameworks of supersymmetry breaking.
With these radiative phases of gaugino masses and scalar couplings, a complex
phase of Higgs holomorphic mass parameter is generated via
renormalization-group running down to low energy. It is found that its phase
value is mainly controlled by wino as well as gluino, which generally receive
different radiative corrections to their complex phases, even if the leading
part of mass parameters follow from the universality hypothesis. The
radiatively generated phases are constrained by the existing experimental
bounds on electric dipole moments, and may be detectable in future
measurements. They are also found to be available for the cancellation
mechanism to be worked.
