Investigation of applicability of extrapolation method for sample field determination in single-yoke measuring setup

In this work the single-yoke measuring technique is proposed to be optimized by extrapolation of a magnetic field profile to the sample surface for determination of the “real” field inside the sample. It has been shown that this approach gives reasonable values of magnetic parameters and allows to solve the well-known problem of considerable fluctuations of the measurement results due to imperfections of the yoke–sample contact. The magnetization process with the single-yoke setup is considered on basis of the surface field measurements around the sample and their extrapolation to the sample surfaces. Advantages as well as drawbacks of the measuring procedure and of the suggested optimization method are discussed.
