Magnetoresistance and magnetization oscillations in Fe/Cr/Fe trilayers

Experimental studies of the magnetooptical and electrical transport properties of Fe/Cr/Fe magnetic trilayers show that a 2-monolayer (2-ML) oscillation period characterizes the magnetoresistance of the trilayers. Antiferromagnetic properties of the Cr interlayer are responsible for the periodicity. The magnetoresistance loops of the trilayers reveal specific steps that reflect the magnetic field values responsible for altering magnetization.
