The Ferromagnetic Domain Structure of Thin Single‐Crystal Fe Platelets in an External Field

Abstract

Abstract The domain structure of small iron single‐crystals in the shape of thin rectangular platelets is studied by means of a colloid technique during magnetization. The observations indicate that the demagnetizing field of the sample is formed by charges on the domain walls. Changes in the domain structure are compared with a magnetization curve obtained by measuring the areas of individual domains.
