摘要
The magnetic reversal in polycrystalline iron foils was investigated by means of Lorentz microscopy at 4 to 300 °K no usual Barkhausen jumps exist. The wall motion of cross‐tie walls consists of small‐size (55 to 3000 å) Bloch line jumps, formation of bordering domains of the order 1 × 1 μm2, and their reversal by rotation. Above a minimum field these processes proceed at constant field. This aftereffect in constant field is influenced by crystal defects. Copyright © 1969 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim
