摘要: We have enhanced the flipping ratio of spin-polarised-neutron near-critical-angle reflectivity measurements by sandwiching thin (few atomic layers) magnetic films (area 2 cm2) between non-magnetic materials, thereby producing interference in neutron wave field within sandwich structure. A strongly spin dependent is observed for a 12 ? polycrystalline Fe film at 300 K but no dependence ultrathin f.c.c. K.
