We report that magnetic properties of an Fe-6.5 wt. % Si alloy can be improved through texture control by using directional recrystallization. Columnar grain structures with column sizes of {approx}0.38 x 1.2 mm{sup 2} were developed during directional recrystallization. It was found that there are low energy boundaries between columns and main textures of the specimen were {l_brace}110{r_brace}<111> and {l_brace}111{r_brace}<110>. As a result, the coercivity of a directionally recrystallized specimen is reduced by a factor of 5 when measured along 60{sup o} away from the growth direction, as compared to a specimen consisting of {approx}77 {micro}m equiaxed grains.
