1.概要(Summary )
The morphology, composition, crystalline structure, and chemical states of elements for mixed nickel-manganese cobaltite (NMCO) nano- particles were analyzed.

2.実験(Experimental)
JEOL JEM-ARM200F scanning transmission electron microscope and Shimadzu Kratos AXIS-ULTRA DLD X-ray photoelectron spectrometer were used.

3.結果と考察(Results and Discussion)
TEM, HRTEM, and STEM-HAADF observations revealed that all obtained cobaltites have polyhydral shape. Their SAED patterns were similar to those of nickel cobaltite and XPS measurements indicated the presence of all elements of interests (Ni2+, Ni3+, Mn2+, Mn3+, Co0, Co2+, Co3+, and O)

STEM-HAADF images and corresponding STEM-EDS elemental mappings of NMCO nanoparticles

XPS spectra of Ni 2p (a), Co 2p (b), Fe 2p (c), O 1s (d) in NMCO nanoparticles.
