文摘

Iron-doped SnO2 diluted magnetic semiconducting powders (Sn1?em class="a-plus-plus">x Fe x O2, x=0.00, 0.03, 0.05, 0.07, 0.10, and 0.15) were synthesized by a simple solid state reaction followed by vacuum annealing and studied the effect of Fe dopant concentrations on structural, optical, and magnetic properties of the synthesized samples. From the X-ray diffraction, it was confirmed that the samples prepared at lower dopant concentrations were tetragonal in structure whereas the samples prepared at higher dopant concentration exhibited orthorhombic SnO and Fe2O3 phases along with tetragonal SnO2 structure. FT-IR spectrum has been used to confirm the formation of Sn–O bond. The optical band gap of the Sn1?em class="a-plus-plus">x Fe x O2 powders was increased from 3.6?eV to 3.7 eV with increase of dopant concentration. Raman spectroscopy measurement revealed that the broadening of the most intense Raman peak observed at 630 cm? with Fe doping, conforming that the Fe ions are substituted at the Sn sites in the SnO2 lattice. Vibrating sample magnetometer measurements confirmed that the Sn1?em class="a-plus-plus">x Fe x O2 powders were ferromagnetic at room temperature.
