Samples of La{sub 0.4}Bi{sub 0.6}Mn{sub 1−x}Ti{sub x}O{sub 3} have been prepared and their microstructure, composition, and magnetic properties have been investigated for x = 0.05, 0.1, and 0.5.The deviation in the inverse susceptibility behavior from Curie-Weiss law and increase in susceptibility exponent indicates the evolution of the Griffith's phase in La{sub 0.4}Bi{sub 0.6}Mn{sub 1−x}Ti{sub x}O{sub 3} around T{sub C}. The presence of Griffith's Phase is inferred due to magnetic frustration with increasing Ti concentration. The deviation between field cooled and zero field cooled magnetization curves is observed in these samples and is attributed to the appearance of the spin glass or cluster glass state that arises due to the magnetic anisotropy.
