Altermagnets combine ferromagnet-like spin splitting with zero net magnetization, but their globally compensated spin textures make spin-polarized transport difficult. Liu et al. show that the hyperbolic Fermi surface of the d-wave altermagnet KV2Se2O turns crystallographic spin segregation into an interfacial tunneling filter: a KV2Se2O/Bi2O2Se/KV2Se2O junction transmits almost purely one spin channel and yields a giant tunneling magnetoresistance of 2,240% field-free, with thermally driven spin filtering surviving to room temperature. The results offer a scalable route to altermagnetic spintronics.
