Abstract: We have studied the magnetic field dependences of the real (chi) and imaginary (chi') contributions to the low-frequency magnetic susceptibility in epitaxial antiferromagnetically coupled [Fe(Cr(1 0 0)](n) (n = 10-50) multilayers. For the magnetic field directed along (1 1 0), the magnetic susceptibility shows on orientation phase transition. For the magnetic field either along the easy or the hard axes we observe a strong enhancement of the chi'(H) (i.e. magnetic losses) at low magnetic fields (H < 50 Oe), which we relate to AC field-induced domain wall movement. This response is strongly dependent on frequency and temperature. (C) 2001 Elsevier Science B.V. All rights reserved.
