چکیده انگلیسی
Cation-doped (Sr2-3xGdxBa2x) FeMoO6 (x= 0.00, 0.05, 0.10, 0.20, 0.25) compounds were synthesized via a standard high-temperature solid-state reaction. The crystal structure and magnetic properties of these samples were analyzed. X-ray powder diffraction analysis showed that all samples are single phase and belong to the I4/m space group. The order degree of Fe/Mo decreased from 91.72% to 83.22%. Magnetic measurements showed that all samples underwent paramagnetic to ferromagnetic (FM) phase transition near the Curie temperature (TC). The main reason for TC reduction could be antisite defect detected by establishing the derivative dM/dT. All samples exhibited FM characteristics by detecting the hysteresis loops of (Sr2-3xGdxBa2x) FeMoO6 at 5â¯K. The configuration scheme of the unit moment for (Sr2-3xGdxBa2x) FeMoO6 can be deduced by magnetic measurement.
