In this work, we have explored the potential of a relatively new class of Pd-based Heusler alloys as permanent magnets. Our approach began with a high-throughput study using the Automatic Flow (AFLOW) electronic structure database to identify Pd₂YZ-type Heusler systems with tetragonal symmetry and high magnetization. For the alloys that passed our initial selection filters, we performed a detailed investigation of their magnetic properties using density functional theory (DFT) calculations. These calculations included assessments of magnetocrystalline anisotropy energy (EMCA) and exchange interactions. The selected candidates, which met all our criteria, were then subjected to Monte Carlo simulations to analyze the temperature dependence of their magnetization and determine their Curie temperatures (TC). Our results indicate that Pd₂FeNi and Pd₂FePt are promising candidates for permanent magnets. Pd₂FeNi exhibited an EMCA of 2.4 MJ/m3 and a TC of 504 K, while Pd₂FePt showed an EMCA of 4.11 MJ/m3 and a TC of 463 K. Both Curie temperatures are significantly above room temperature by more than 160 K, demonstrating the alloys’ potential for high-temperature applications and their overall suitability as efficient, rare earth-free permanent magnets.
