Fig. 3: The in situ process of the formation of magnetism and structural coordination.

SEM images and SAED patterns show the morphologies and crystallinity of a LCPC and b KCPC magnets. c Raman spectra show the shift of molecular vibration peaks between LCPC and KCPC magnets. The solid red and black lines are the smoothed results. d FTIR spectra of LCPC and KCPC magnets indicate the absorption of molecular vibration changes with alkali-metal substitution.
