Phys. Rev. Lett. 50, 2024–2027 (1983)New Class of Materials: Half-Metallic FerromagnetsReceived 21 March 1983; published in the issue dated 20 June 1983 The band structure of Mn-based Heusler alloys of the C1b crystal structure (MgAgAs type) has been calculated with the augmented-spherical-wave method. Some of these magnetic compounds show unusual electronic properties. The majority-spin electrons are metallic, whereas the minority-spin electrons are semiconducting. © 1983 The American Physical Society URL:
