摘要：
Cation-doped (Sr(2-3)xGd(x)Ba(2x)) 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 (T-C). The main reason for T-C 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 5 K. The configuration scheme of the unit moment for (Sr2-3xGdxBa2x) FeMoO6 can be deduced by magnetic measurement.
