Corrigendum to “Effect of Ce–Dy rare earths co-doping on various features of Ni–Co spinel ferrite microspheres prepared via hydrothermal approach” [J Mater Res Technol, 14, September–October 2021, 2534-2553] (Journal of Materials Research and Technology (2021) 14 (2534–2553), (S2238785421008048), (10.1016/j.jmrt.2021.07.142))

The authors regret inform that there is an error in Fig. 1c in the original published version of the article (https://doi.org/10.1016/j.jmrt.2021.07.142) as one XRD patent x = 0.02 was unintentionally duplicated with x = 0.08 during the process of copying and pasting multiple times between referment software and origin software. Fortunately, no any of the other results were affected by this unintentional error. The corrected version of Fig. 1c is attached. The authors would like to apologise for any inconvenience caused.[Formula presented] Fig. 1. (a) The cubic unite cell of Ni_0.5Co_0.5Ce_xDy_xFe_2-2xO₄ SFMCs, XRD patterns of (b) carbon microsphere and (c) Ni_0.5Co_0.5Ce_xDy_xFe_2-2xO₄ (x ≤ 0.10) SFMCs.
