We report here for the first time colossal magnetoresistance effects (~77% MR at 5 T) in bulk single crystals of self-doped La 0.936 Mn 0.982 O 3 prepared by fused-salt electrolysis. The crystals form with rhombohedral symmetry and show a high degree of perfection by electron backscatter diffraction. The maximum in the MR% was observed in the vicinity of ~250 K where the crystals undergo a sharp insulator-to-metal as well as a paramagnetic-to-ferromagnetic transition.
