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 to act as the additive in the preparation of yttrium iron garnet (YIG) nanoparticle precursor (ACP). The ACPs and YIG nanocrystal were identified by using Fourier transfer infrared spectrophotometry (FT‐IR), inductively coupled plasma (ICP), X‐ray diffraction (XRD) spectra, and transmission electron microscope (TEM) micrograph, respectively. Compared to the traditional YIG preparation, the well‐formed YIG nanocrystal could be obtained by using this ACP precursor at a low calcination temperature of 600°C. In addition, the more amount of the chelating group was added, the higher purity of the YIG nanocrystal was obtained. Furthermore, the YIG nanocrystal obtained by using the ACP precursor had a nearly superparamagnetic behavior and their saturated magnetic property was around 5.7–41.9 emu/g after the vibrating sample magnetometer (VSM) examination. In summary, the chelating polymer additive improves not only the crystallinity of the YIG nanocrystal but also magnificently decreases the sintering temperature of the YIG nanocrystal.
