Abstract
We report the successful growth of high-quality Sr 3Fe 2O 7− x single crystals with volumes of up to 0.3 cm 3 by using the floating zone method. Compositional homogeneity of the crystals was verified by powder X-ray diffraction, optical and electron microscope measurements. The X-ray rocking curves of the Sr 3Fe 2O 7− x single crystal gave a full-width at half-maximum (FWHM) of Bragg reflections of 0.02–0.03°. The influence of the growth rate on the crystal size and quality was demonstrated. The effect of oxygen annealing was studied by magnetic susceptibility and Raman light scattering experiments. The Fe(+3)/Fe(+4) ratio was determined both from the magnetization and thermo-gravimetric data.
