Nano-crystalline GdFeO3 was synthesized by three different soft-chemical routes viz. hydrothermal, co-precipitation and combustion. The hydrothermal and co-precipitation methods resulted in amorphous powder which on further heating resulted in GdFeO3. The combustion method produced phase pure GdFeO3 in a single step. The particle size was in the range of 50–70 nm as calculated by Scherrer's formula. The transmission electron micrographs (TEM) showed the presence of fairly regular particles. Magnetic studies revealed a paramagnetic behavior. The magnetic susceptibility (in emu/g-Oe) of GdFeO3 samples as synthesized by hydrothermal, co-precipitation and combustion routes was found to be 9.6 × 10− 5, 6.7 × 10− 5 and 4.4 × 10− 5 respectively.
