“…The T N is found to decrease with increase of Bi doping for x t 0.3. The magnetic states of Bi3, Bi4 and Bi5 samples could be assigned to antiferromagnetic states based on other reports of Bi doped manganites [16,17]. Nevertheless, we have not observed transitions related to charge ordering state in M-T data of Bi3, Bi4 and Bi5 samples with applied field of 1 T. The charge ordered transitions in Bi3, Bi4 and Bi5 samples could possibly be above 390 K [24,29].…”
