Phys. Rev. B 62, 16018–16022 (2000)Interlayer coupling in Co/Si sandwich structuresReceived 6 March 2000; revised 1 August 2000; published in the issue dated 15 December 2000 The combinations of magnetic materials with traditional semiconductors are interesting possibilities for new magnetoresistive structures. In this work the interlayer magnetic coupling in Co-Si systems has been studied. The coupling has been calculated within the density-functional theory, and it has been observed to oscillate with a spatial period of two Si layers. The electronic structure analysis indicates the formation of quantum wells within the Si spacer. © 2000 The American Physical Society URL:
