- The X-ray photoelectron spectra for Re$\text{}_{3}$Fe$\text{}_{5}$O$\text{}_{12}$ garnets, ReFeO$\text{}_{3}$ orthoferrites and ReVO$\text{}_{4}$ orthovanadates have been measured by using Mg K$\text{}_{α}$ radiation. The O 1s, Re 4d, Fe 2p, and V 2p photoelectron spectra were studied. A very big difference was observed between ReFeO$\text{}_{3}$ orthoferrites and ReVO$\text{}_{4}$ orthovanadates, mainly the Fe 2p $\text{}_{3}\text{}_{/}\text{}_{2}$ lines were double broader than V 2p $\text{}_{3}\text{}_{/}\text{}_{2}$ ones, and the O 1s line is split by about 1.6 eV for orthoferrites, while this line is single for orthovanadates. The O 1s peak at 531.8 eV with intensity about 70% of the main peak is interpreted as originated from a charge fluctuation between oxygen and iron ions due to superexchange interaction.
