Abstract: Results obtained by perturbed-angular-correlation (PAC) spectroscopy on epitaxial chromium thin films are compared with data obtained from the same samples by neutron-diffraction experiments. We report on the study of a 250-nm-thick Cr single layer and an Fe/Cr multilayer with Cr thickness of 25 nm grown on Nb/Al2O3 (1102). The chromium single layer film orders below the Neel temperature as a longitudinal (AF) spin density wave antiferromagnet with the spins out of plane, while the Cr in the Fe/Cr multilayer orders as a transversal (AF(1)) spin density wave antiferromagnet with the spins in plane. In addition we observe a minority volume fraction in a commensurate AF(0) phase, stable up to at least 400 K. The present results prove that PAC probes the intrinsic magnetic features of chromium and therefore validate this technique as a complementary approach towards the understanding of the chromium magnetism in thin films and Fe/Cr multilayers.
