Popis:	A 20 × [Fe(20 A)/Cr (12 A)]/MgO structure excited by an ultrasonic wave was investigated by polarized neutron reflectometry. It was found that magnetic domains oscillate and their effective size decreases in weak magnetic fields. In close-to-saturation fields, a magnetic lattice is formed in the layered structure; the interplanar spacings in this lattice change with an increase in the field strength and as a result of the excitation of the structure by an ultrasonic wave.
