Since Fe has a transformation point, a single crystal cannot be grown, but a single crystal growth in a Fe-Si solid solution is possible. This time, we succeeded in pulling up a Fe-Si single crystal with a size of φ35 mm and a straight body of 65 mm. The Si composition of the grown crystal was evaluated by X-ray fluorescence, and it was confirmed that the Si composition was 5.7 at%. In order to compare with the Fe0.82Si0.18 single crystal that has already been developed as a magnetostrictive material, a diameter of 2 inches or more is prepared, and the crystal quality and workability are investigated and reported.
