Notes:
A short period oscillation was observed in the interlayer exchange coupling of sputtered Co-Re superlattices, superimposed on a long period oscillation. This effect is observed on hcp-textured samples with the c axis perpendicular to the plane of the film. The variation of the exchange coupling strength with the spacer thickness can be described using the Bruno and Chappert theory with two oscillatory terms, with periods of 2.9±0.2 and 10.2±0.2 A(ring). Both magnetization and magnetoresistance measurements reflect the influence of this multiperiodic exchange.
