简介：DyPt2filmswerepreparedbyalternatedepositionthinDyandPtlayersonglasssubstratesbyDCmagnetocontrolledsputteringmethod.TheXRDdataindicatedthatforas-depositedDy/Ptfilms,andtheperiodiclayeredstructuresalongthicknessdirectionwereevidencedwithlowangleX-rayscattering.Withincreasingannealingtemperature,thecompoundsofDyPt,DyPt2andDyPt3wereformedsuccessivelyattemperaturerangingfrom300to400℃.ItwasfoundthatthecompositionreactionDyPt+DyPt3→2DyPt2tookplaceat500℃.Afterannealingat500℃for1h,thecompoundsDyPtandDyPt3transformedcompletelyintotheDyPt2compound.
