| 摘 要： | 1 Results Yttrium iron garnet (YIG) is a well-known ferromagnetic garnet material and has widely used in electronic devices1].A new acrylic chelating polymer was developed to act as the additive of the preparation of YIG precursor in our previous study2].The sintering temperature of YIG nanocrystal obtained by this YIG precursor (ACP) was magnificently descended from 1 000 to 600 ℃.In this study,we were further to study the effect of amount of chelating polymer and the compositions of chelating polymer on the YIG nanocrystal preparation and its magnetic properties.A series of the acrylic chelating polymer,poly(butyl acrylates-co-glycidyl methacrylate-co-2-methylacrylic acid 3-(bis-carboxymethylamino)-2-hydroxy-propyl ester) was prepared by using soap-free emulsion polymerization.
