An electron microscope with electrostatic lenses was used for high resolution studies of magnetic domains in thin iron films.
Observation methods used to determine the directions of local magnetization in iron thin films were the Lorentz method and the Foucault method.
We studied how Bloch line-crosstie pairs and crosstie main walls behave in applied, in-plane magnetic fields. We found that crosstie main walls remain unchanged until crosstie density goes nearly to zero when the field is applied perpendicular to the main wall. A twisted type of domain appears where crossties disappear.
