NdFeO 3 single crystals have been grown by optical floating-zone technique using Nd 2 O 3 and Fe 2 O 3 as the source by solid-state reaction method. The crystalline structure of NdFeO 3 belongs to orthorhombic symmetry and the presence of a distorted perovskite structure was confirmed by powder X-ray diffraction (XRD) analysis. From the XRD results, it is visualized that the lattice expansion has been observed in the unit cell parameters which may appear due to interstitial defects in the NdFeO 3 matrix. The deficiency of oxygen atoms and the presence of excess Fe ions in NdFeO 3 have been confirmed with EDX spectra. The spin-reorientation region ( T = 120 K) exhibits lower coercive field and the hysteresis loops depict enhanced magnetization ( M s and M r ) values of NdFeO 3 single crystal. Presence of compensation temperature point at T comp = 7.5 K denotes the anti-parallel alignment of rare-earth ions with Fe magnetic moments. At high temperatures, Fe 3+ magnetic moments show strong antiferromagnetic interactions ensuing in Neel temperature ( T N ) at 690 K.
