The decays [ital t][r arrow][ital cV] ([ital V]=[gamma],[ital g], or [ital Z]) induced through loop processes are calculated in the minimal supersymmetric model. We find that these new contributions can enhance the standard model branching fractions by as much as 3--4 orders of magnitude, i.e., [ital B]([ital t][r arrow][ital cg])[similar to]10[sup [minus]6], [ital B]([ital t][r arrow][ital cZ])[similar to]10[sup [minus]8], and [ital B]([ital t][r arrow][ital c][gamma])[similar to]10[sup [minus]8], for favorable values of the parameters.
