TI Magnetoresistance and magnetization of Fe/Cr(001) superlattices
   with noncollinear magnetic ordering
SO PHYSICAL REVIEW B
AB We study the magnetization and magnetoresistance of
   superlattices with biquadratic exchange. The equilibrium states
   are analyzed on the base of the free energy expression that
   includes all terms up to the fourth order in components of
   magnetizations of magnetic sublattices. The con-elation between
   the magnetization curve and the magnetoresistance for various
   orientation of magnetic field relative to the film plane is
   established. The experimental studies are made on the samples
   of molecular-beam epitaxy grown Fe/Cr superlattices. The
   positive magnetoresistance was found for the perpendicular-to-
   plane magnetic field. It is shown that this effect as well as
   the characteristic features of the magnetization curves are
   connected with the noncollinear magnetic alignment, which
   exists in our samples, and the fourth order magnetic anisotropy
   of unfamiliar type.
