From the comparison of B(H) curves measured in SST and RSST on grain-oriented SiFe sheets with high anisotropy follows that the correlation between them is doubtful. It is mainly due to strong influence of the shape anisotropy in the case of SST interacting in complicated way, owing to nonlincarity, with the magnetocrystalline anisotropy. The results obtained in RSST which provides the possibility of controling VB are closer to the real situation in such magnetic circuits where the vectors B and H are deviated from the rolling direction. The aim of presented paper is to answer the question to which extend correlate the SST and RSST experimental results and to prove the assumption about the reason of discrepancies.
