We report an experiment on magnetic or magneto-electric annealing effects using a single crystal of (Cr2O3)0.99-(Al2O3)0.01. The transition of antiferromagnetic domain was observed through the measurement of sign and magnitude of the magneto-electric coeffi-cient α. From these experimental results we found that the 180° reversal of all spins could be induced by the electric field when the sample was cooled through N'eel temperature under the applications of magnetic and electric fields. Moreover the threshold value EH which gives the reversal of α' s sign was found to be a constant.
