Large PrFeO3 single crystal 45mm in length and 6mm in diameter was successfully grown by the floating zone technique using a four-mirror-image-furnace at 2mm/h growth rate under flowing air. XRD pattern and X-ray back-reflection Laue photograph indicated good quality of the as-grown PrFeO3 single crystal and confirmed [110]-orthorhombic orientation along the grown direction. Fe/Pr ratio fluctuates a little in different zones and has a slight Fe deficiency in the sediments. The evident magnetic anisotropy was observed by comparing the magnetization with H⊥(110) and H(110), and confirmed the good quality of the as-grown crystal. Pr3+ moments align from the paramagnetic state into the antiferromagnetic state below 7.6K.
