Abstract
Polarised neutron reflection measurements are reported for Ag/Cr/Ag(001) sandwich structures. For a Cr layer equivalent to a coverage of 0.33 monolayers, the data suggest long-range ferromagnetic order with a magnetic moment per atom that is significantly greater than the bulk value. For a 3.3-monolayer-thick layer, no ferromagnetism is detected.Keywords
