Synthesis and magnetic property of FeMoO4 nanorods

Monoclinic FeMoO4 nanorods have been prepared by the hydrothermal method in an acid aqueous solution. Scanning electron microscopy, transmission electron microscopy, X-ray diffraction spectrum, X-ray photoelectron spectra and differential scanning calorimetry are used to characterize the structure, morphology and composition of the sample. The FeMoO4 nanorods exhibit a ferromagnetic property at room temperature with the coercivity of 31.1 Oe and remnant magnetization of 4.09 × 10−3 emu/g, respectively. The magnetic mechanism has been discussed according to the calculated results of electron density of states for FeMoO4 with consideration of oxygen vacancies by using the Vienna ab initio simulation package.
