There are theoretical speculations that the top quark may have different properties from that predicted by the standard model. We use an effective Lagrangian technique to model such a nonstandard top quark scenario. We parametrize the [ital CP]-violating interactions of the top quark with the bubble wall in terms of an effective top quark Yukawa coupling, then study its effects on electroweak baryogenesis. We also discuss the phenomenology of such an effective Yukawa coupling in low and high energy regions.
