Abstract

Two different types of antiferromagnetic (AF) interlayer couplings as a function of Si layer thickness, tsu have been observed in a series of (2.6 nm Fe/t_Si nm Si)₂₂ multilayers. One of the AF-couplings was observed at around t_Si = 1.2 nm at room temperature (RT) and changed to ferromagnetic (F) coupling at a low temperature. The other AF coupling was observed for t_Si thicker than 1.5 nm with a minimum around t_Si = 2.5 nm, and was almost temperature independent. Negative magnetoresistance has been observed in the multilayers with the AF coupling, and has similar temperature dependence as that of the AF coupling.
