Electronic structures and half-metallicity at ferromagneticantiferromagnetic (AFM) interfaces in zincblende transition-metal chalcogenides, CrSeMnSe and CrTeMnTe, are investigated by means of the first principles full-potential linearized augmented plane-wave method within the LDA+U, and the effect of correlation in the 3d states on the half-metallic interfaces is discussed. The uncompensated AFM interface with the antiparallel alignment of the Cr and Mn moments at the interfaces shows an excellent half-metallicity, where the correlation effect tends to manifest the half-metallic interfaces. This indicates that these interfaces offer a key ingredient as promising exchange bias candidates in having interfaces with 100% spin polarization at the Fermi level.
