INVESTIGATION OF THE ROLL MAGNETIC-ANISOTROPY BY MEANS OF THE MOSSBAUER-EFFECT

Changes in the spin orientation in cold-rolled Fe-12 at% Si alloy samp les were studied by means of the Mossbauer effect. In the deformed str ucture two components were distinguished: high dislocation density reg ions (HDDRs) and original crystalline structure with low dislocation d ensity. It is shown that spins are reoriented by cold-rolling toward t he sheet plane and rolling direction in both components but in HDDRs t his orientation is more pronounced. The results indicate that HDDRs ha ve the dominating influence on the spin reorientation in the whole vol ume of the sample.
