Abstract (in Japanese) (See Japanese page) 
(in English) Fe-Co-B alloy films of 40 nm thickness are prepared on MgO(001) single-crystal substrates using alloy targets of (Fe0.7Co0.3)100–xBx(x = 5, 10, 15 at. %)by varying the substrate temperature from room temperature to 600 C. The effects of B composition and deposition substrate temperature on the crystallographic and the magnetic properties are investigated by reflection high-energy electron diffraction, X-ray diffraction, atomic force microscopy, and vibrating sample magnetometry. (Fe0.7Co0.3)100–xBx(x = 5, 10, 15 at. %)films with bcc structure grow epitaxially on MgO substrates at temperature regions of 200–600 °C, 400–600 °C, and 600 °C, respectively. The structure of Fe-Co-B alloy film changes from bcc(001) single-crystal to amorphous with increasing B content and decreasing substrate temperature. The structures of Fe-Co-B alloy films on MgO(001) substrate are classified into four structure types, bcc(001) single-crystal, mixed structure of bcc(001) and bcc(122) crystals, polycrystal, and amorphous. The coercivity increases with increasing the substrate temperature.
