The authors regret errors in Fig. 2a, b, d and g in the originally published article [1]. In Fig. 2a, b and d, the TEM/HRTEM images and the magnetic curve of FMSPs were not the correct ones. These mistakes came from the confusion of the images and the curves. In Fig. 2g, the authors wish to use the different PL excitation and emission spectra of FMSPs to their another article. The authors apologize for these mistakes and are now providing the correct TEM/HRTEM images and magnetic curve, and the new PL excitation/emission spectra of FMSPs in Fig. 2. All the data herein are accurate and reproducible. These corrections do not affect the conclusion of this article.
