In the present study, the melt with Nd(x)Sm(3-x)Fe5O12 composition was undercooled in an aerodynamic levitator and splat-quenched by copper anvils in order to obtain the metastable garnet phase with the lattice parameter greater than MLC (x = 0.38). X-Ray Diffraction (XRD) results indicated that the peak intensity of metastable garnet phase decreased with increasing the substitution x from 0.38 to 0.2 and finally disappeared at x = 2.2. The metastable garnet phase possessed the same composition as the starting composition. The maximum Nd substitution obtained using the splat quenching method was x = 2.0. Moreover, the amorphous phase was found in the central part of the sample, which was confirmed by micro focus XRD., 資料番号: AA0048095004}, pages = {13--16}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {急冷凝固法を用いた準安定希土類鉄ガーネットの生成}, year = {2005} }
