Abstract

Sample of Bi0.3Pr0.3Ca0.4Mn1-xCrxO3(0≤x≤0.14) and Bi0.3-xLaxPr0.3Ca0.4Mn0.9Cr0.1O3 (0≤x≤0.2) were prepared by solid state synthesis method to elucidated the structural, magnetic properties and electrical transport in bismuth based-manganite. For Bi0.3Pr0.3Ca0.4Mn1-xCrxO3 R versus T curve shows that x=0 sample exhibited a strong insulating behaviour, and Cr3+ substitution at x=0.08 induced metal-insulator (MI) transition at MI temperature (TMI) of 56 K. For x=0.08 sample can successfully weaken the hybridisation effect through the strong ferromagnetic (FM) interaction.
