摘要: Abstract We performed polarized neutron reflectometry (PNR) experiments on a 29 nm thick Au93Fe7 film in temperature range from 295 K down to 2 K vertical magnetic field up 6 T. These high-field were the C5 spectrometer Chalk River, Canada, using split-pair cryomagnet. The magnetization as determined by PNR can be described with Brillouin function 50 K assuming moment of isolated Fe atoms, i.e. 4 μ B per atom. Below onset spin-glass freezing is observed strong deviation this type behavior atoms.
