摘要：
In this paper, permalloy films containing artificially created nanoscale perforations are studied, and it is theoretically substantiated that in the region of a pair of closely spaced perfo-rations, the formation of topologically protected vortex-like inhomogeneities is possible. Quantita-tive estimates of the conditions for the existence of inhomogeneities of this type are obtained, and the causes and possible scenarios for their destruction are studied in cases where these conditions are violated.
