Abstract

The critical properties of polycrystalline Pr1−xBaxMnO3 (x = 0.13 and 0.23) samples prepared by using a standard ceramic fabrication method were investigated. Pr1−xBaxMnO3 exhibited a second-order magnetic transition. As per the modified Arrott plot method and double logarithmic M0H curve, the critical exponents (CE) were calculated as β = 0.459 ± 0.03, γ = 1.346 ± 0.02, δ = 4.32 ± 0.04, and TC  130 K, for x = 0.13, and β = 0.424 ± 0.03, γ = 1.362 ± 0.02, δ = 4.19. ± 0.03, and TC  163 K, for x = 0.23. To confirm the reliability of such CE values, the M (H) data of Pr1−xBaxMnO3 were checked by the scaling equation M(H, t) = |t|βf±(H/|t|β + γ), where \( t=\frac{T}{T_C}-1 \) refers to the reduced temperature, f± is the scaling function above (+)/below (−) TC. The β values for Pr1−xBaxMnO3 (x = 0.13 and 0.23) are between β = 0.365 (3D Heisenberg exponent) and β = 0.5 (mean-field exponent), whereas γ values are fairly close to γ = 1.386. This reveals long- and short-range order coexisting in Pr1−xBaxMnO3.
