In this chapter, crystallographic data, bulk modulus and magnetic properties of GdFeO3 are given. Graphical representation of pressure dependence of the magnetic hyperfine field of GdFeO3 are also discussed here.
The crystal structure of gadolinium orthoferrite, GdFeO 3, has been determined from single‐crystal x‐ray data. There are four GdFeO 3 distorted perovskite units in the orthorhombic cell with …
The Rietveld refinement of XRD pattern confirms the orthorhombic structure of the GdFeO3 nanomaterial with the Pbnm space group. SEM analysis reveals that the particles exhibit dimensions within the nano regime. FTIR and Raman spectra show the presence of all the modes associated with GdFeO3.
Single phase Gadolinium orthoferrite (GdFeO 3) with orthorhombic perovskite structure was synthesized without any garnet impurities by solid state reaction and subsequently GdFeO 3 single crystals were grown by the optical floating zone technique.
GdFeO 3 nanoparticles were fabricated by a facile metal–organic precursor method using citric acid as a complexing agent. The phase purity and structural analysis by powder X-ray diffraction and FTIR studies indicates that …

Intriguingly, the broad region of magnetic field (0–3 T) showing the irreversibility of heat transport coincides with that presenting the ferroelectricity. It is discussed that the …
GdFeO 3 nanoparticles were fabricated by a facile metal–organic precursor method using citric acid as a complexing agent. The phase purity and structural analysis by powder X-ray diffraction and FTIR studies indicates that the material is highly crystalline with an orthorhombic structure.
Intriguingly, the broad region of magnetic field (0–3 T) showing the irreversibility of heat transport coincides with that presenting the ferroelectricity. It is discussed that the irreversible behaviors are due to the phonon scattering by ferroelectric domain walls.

The crystal structure of gadolinium orthoferrite, GdFeO 3, has been determined from single‐crystal x‐ray data. There are four GdFeO 3 distorted perovskite units in the orthorhombic cell with lattice constants a =5.346, b =5.616, c =7.668, all ±0.004 A. The structure is solved on the basis that the most probable space group is D 2h (16)— Pbnm.
Here, we investigate the electronic structure, magnetism and optical properties of orthorhombic GdFeO 3 in terms of density-functional-theory calculations. The modified Becke-Johnson (mBJ) exchange potential is adopted to improve on the description of …
