In this review, on the basis of our recent theoretical and experimental studies, we discuss the magnetic and electrical properties of γ-phase and Ll_0-type antiferromagnetic Mn alloys. The point we wish to stress is that the calculated electronic properties are consistent with the experimental magnetic and electrical resistivity data. Especially, the spin structures and the pseudo-gap at the Fermi level are closely correlated with the antiferromagnetic stability. Our mechanism of the exchange bias-field well describes the biasing properties under the conditions with various spin structures. From the practical viewpoint for spintronic devices, the magnetovolume and elastic properties are also discussed.
