摘要：

Two distinct single phases of ferromagnetic LaMn0.5Co0.5O3 have been synthesized by the low-temperature glycine-nitrate method. Sample heated to 700 degreesC shows a single well-defined ferromagnetic transition at T-c approximate to 225 K whereas the sample heated to 1300 degreesC shows a sharp ferromagnetic transition at T-c approximate to 150 K. Mixed phase behavior is observed for samples heated in the temperature range 700-1300 degreesC. (C) 2000 Elsevier Science B.V. All rights reserved.
