Polarized-neutron reflectivity together with magnetization and magnetotransport measurements on a (001)-oriented [Fe(14 A)/Cr(74 A)]{sub 20} superlattice confirms the existence of 90{degree} alignment of adjacent Fe layers due to biquadratic interlayer coupling. Each Fe layer is in a single domain state and the magnetic structure is coherent throughout the layered stack. The biquadratic coupling, however, is suppressed below the Cr N{acute e}el temperature ({ital T}{sub {ital N}}=187 K) as the Fe layers uncouple. But by field cooling through {ital T}{sub {ital N}} it is possible to retain a metastable biquadratic arrangement. {copyright} {ital 1996 The American Physical Society.}
