Abstract: We compare the results obtained by the perturbed angular correlation (PAC) technique with data obtained from the same samples by neutron diffraction experiments. We report on the study of a 250 nm thick Cr film and an Fe/Cr (25 nm) multilayer grown on Nb/Al2O3 (1 1 0 2). The chromium film orders below T-N = 330 K as a AF(2) SDW with the spins out-of-plane, while the Cr in the Fe/Cr multilayer orders as an AF(1) SDW with the spins in-plane. In these samples, we no observe a minority volume fraction in the AF(0) phase, stable up to at least 400 K. These results validate PAC as a complementary approach towards the study of the Cr magnetic ordering in thin films and Fe/Cr multilayers. (C) 1999 Elsevier Science B.V. All rights reserved.
