Abstract In order to study the effect of the uniaxial stress on the development of a cube-on-face texture, two sheet samples were heat treated with different positions to have a different self-load, resulting in a different stress. One specimen was heat treated at 1120 °C for 60 min with the broad face positioned horizontally to the specimen holder and the other specimen was heat treated with the broad face positioned vertically to the specimen holder with the other condition being the same. The former produced a weak {1 0 0}  texture, being only 30.9% whereas the latter produced a strong{1 0 0}  texture, being 81.1%. We found out that such a texture difference is related to the difference in the nucleation barrier coming from the stress disparity. Based on this understanding, specimens with a different percentage of the {1 0 0}  texture could be manufactured. The measurements of magnetic properties showed that the specimen with 78.4% of {1 0 0}  and 3.2% of {1 1 1}  had B50 = 1.75 and W15/50 = 2.19, but the specimen with 0.7% of {1 0 0}  and 81.3% of {1 1 1}  had B50 = 1.61 and W15/50 = 2.50. The results show that the magnetic flux density of B50 was increased by 8.7% and the eddy current loss of W15/50 was decreased by 12.4% due to the evolution of the {1 0 0} texture.
