초록

Anistropic [Ta/NdFeB/Ta] thin film was sputtered on heated Si substrate by Nd$\_$17/Fe$\_$74/B$\_$9/ target. The grain size of the films increased according to the increase of substrate temperature, and the film deposited at 650$^{\circ}C$ showed optimum coercivity. 4$\pi$M$\_$r/, $\_$i/H$\_$c/ and (BH)$\_$max/ measured perpendicular to the film plane of thin film deposited at 650$^{\circ}C$ are 12.3 kG, 9.9 kOe and 37 MGOe, respectivly.
