AB - The magnetocaloric effect (MCE) offers a promising route toward eco-friendly magnetic refrigeration, necessitating air-stable materials with enhanced performance. In this work, we explore the tuning of MCE in antiferromagnetic CaMnO<inf>3</inf> via slight Praseodymium (Pr) doping. Ca<inf>1−x</inf>Pr<inf>x</inf>MnO<inf>3</inf> (x = 0.05, 0.10) compounds were synthesized and systematically characterized. Pr incorporation significantly enhances the magnetic entropy change by modulating exchange interactions through compositional tuning. X-ray photoelectron spectroscopy confirms an increased Pr<sup>4+</sup> concentration, which shifts the Mn<sup>3+</sup>/Mn<sup>4+</sup> ratio and strengthens Mn<sup>4+</sup>–O–Mn<sup>3+</sup> exchange interactions, thereby improving the MCE response. These findings highlight the efficacy of rare-earth doping in optimizing magnetocaloric properties and provide a framework for designing advanced MCE materials.
