The temperature dependence of the resistance and magnetization of Bi 3+ ‐doped (La 0.83 Bi 0.17 ) 0.67 Ca 0.33 MnO 3 is investigated, for which both thermal and magnetic hysteresis phenomena are observed. In a lower applied magnetic field range of 0 < H < 0.5 T and a temperature range of 110 < T < 200 K, a two‐step magnetization behavior with an enhanced magnetoresistance effect is observed. According to the experimental results, it is surmised that the hysteresis behavior results mainly from the coexistence of charge ordered (CO) and ferromagnetic (FM) domains, for which the CO domains have relaxation and pinning effects on the growth and rotation of FM domains.
