The peculiarities of behavior of nuclei remagnetization in a magnetic field in uniaxial films

The influence of magnetic field on the structure and properties of magnetic inhomogeneities generated in the defects of the type of “potential well” in magnetic uniaxial films has been theoretically investigated. It is shown that the behavior of high-amplitude and low-amplitude inhomogeneities in the magnetic field varies considerably, and the causes of such differences are identified. It is established that in some cases, when these inhomogeneities do not exist in the absence of a field, they can be induced in a nonzero field. Possibilities to identify both types of heterogeneities at their experimental detection are considered.
