In this article, an effort was made to explore the properties of praseodymium-substituted barium orthoferrites with a better performance in absorption of microwaves. Orthoferrites with BaPrxFe2−xO4 (0 ≤ x ≤ 0.1) were prepared using an ultrasound-assisted sonochemical reactor. In this study, ultrasonic technique was used for the preparation and characterization of BaPrxFe2−xO4 (0 ≤ x ≤ 0.1) materials. X-ray diffraction (XRD) pattern was used to determine the structural properties such as phase purity and crystallite parameters. Analysis of the XRD pattern indicated that the prepared BaPrxFe2−xO4 ferrites have orthorhombic structure with the Bb21 m space group. The temperature-dependent AC susceptibility (χac) and in situ ultrasonic measurements were carried out to explore the Curie temperature of the BaPrxFe2−xO4 samples. Magnetic properties of the prepared BaPrxFe2−xO4 orthoferrites showed narrow M − H hysteresis loops. The coercivity of barium-based samples was found to increase with praseodymium substitution whereas the remenance and saturation magnetization decreased.
