  "abstract": "Fully compensated ferrimagnets, characterized by nearly vanishing magnetic moments at zero temperature, perfect spin-polarized electronic structures, and ultrafast spin dynamics, represent a highly promising materials platform for next-generation spintronic devices. By minimizing stray magnetic fields and reducing switching currents, FCFs enable a viable path toward high-speed, low-power spintronic devices. In this work, we present a systematic investigation of the electronic structure, finite-temperature magnetism, and spin-dependent transport properties of the Heusler-type fully compensated half-metallic ferrimagnet Mn3Al in magnetic tunnel junctions. We demonstrate that Mn3Al is a half-metallic FCF with 100% spin polarization and fully compensated magnetization at 0 K. Combining density functional theory with Monte Carlo simulations, we characterize its finite-temperature magnetic properties and show that Mn3Al exhibits a net magnetization below 11.6 emu/cc at 300 K, confirming the robustness of its nearly compensated ferrimagnetic order at room temperature. Furthermore, we predict that the Mn3Al/MgO/Mn3Al MTJ yields a giant tunneling magnetoresistance effect at 0 K, which remains as high as 232% at 300 K. Our results establish Mn3Al and related half-metallic FCFs as excellent candidates for magnetoresistance-based spintronic applications.",
