Abstract
The behaviour of closure domains at the surface of iron single crystals in an external magnetic field was studied by DPAC on samples implanted with111In. It is observed that the surface magnetization does not follow that of the bulk. The movement of both the 90‡ and 180‡ walls of the closure domains is blocked up to a certain “starting” value Hs of the external field that is related to the demagnetization factor D of the sample and also depends on the precise orientation of the crystal axes and on the implanted indium dose.
