Abstract

The [Fe/Cr]N superlattices with the uniaxial in-plane anisotropy and the stairs-like dependences of magnetization and magnetoresistance on a magnetic field were MBE-grown on special (2 1 1)MgO substrates. It is shown that the "steps" on the M(H) and ΔR/R(H) dependences are results of the multiple spin-flip transitions, i.e. 180°-reorientation of magnetic moments of ferromagnetic sublayers in the superlattices. The transitions are found to be very sensitive to small variations of the Cr layers thickness.
