Antiparallel alignment states are confirmed in Fe/Cr and NiFe(Permallo
y)/Cu/Co/Cu multilayers by polarized neutron diffraction. The magnetor
esistance change is quantitatively related to the square of the differ
ence of magnetization vectors of two magnetic layers when the magnetic
structures are regarded as single domains.
