英文摘要A paramagnetic-ferromagnetic transition was observed in normal spinel zinc ferrite (ZnFe2O4) during atomic hydrogenation at room temperature. Magnetic measurements showed enhanced ferromagnetic property with increasing hydrogenation time. The hydrogenated ZnFe2O4 has normal spinel structure according to X-ray diffraction (XRD) and Raman analyses. Iron hydride was found from the XRD and X-ray absorption fine structure results. No A-B site ions exchange was observed in the x-ray absorption spectra while the atomic distances of Fe-O, Zn-O, Fe-Fe, Zn-Zn and Fe-Zn coordinations were reduced. A hybrid of Fe2+ and Feat in hydrogenated ZnFe2O4 can be further revealed through deconvolution of x-ray absorption near edge structure. The paramagnetic-ferromagnetic transition and enhanced ferromagnetic property were mainly due to the formation of iron hydride and the B-site super-exchange interactions of Fe2+ and Fe3+.
