A study on synthesis and exchange-spring properties of the SrFe12O19/Fe3O4 nanocomposites with core shell structure

Đang chuẩn bị nút TẢI XUỐNG, xin hãy chờ

Two series of SrFe12O19/Fe3O4 nanocomposites were prepared using mechanical mixing method from SrFe12O19 and Fe3O4 nano powders and sol-gel method combined with hydrothermal method. The phase composition, surface morphology and magnetic properties of these samples were investigated using XRD, SEM, Raman and VSM. |
