We report the giant magnetoresistance (GMR) effect in the first non-perovskite compound Tl2Mn2O7 forming in the pyrochlore structure. Our results, furthermore, show that the GMR is greatly enhanced in the miscibility gap region of the quasi-binary phase of Tl2Mn2O7 - In2Mn2O7. Our findings should invigorate the exploration of new GMR materials as well as possible utilization of phase mixing to enhance the GMR effect.
