Abstract: The results of an investigation into square permalloy ﬁlm microdots with a quasivortical magnetic structure by the method of Lorentz electron microscopy are presented. The found before mechanism of the switching of microdot chirality in homogeneous plane magnetic ﬁeld is discussed. The calculations are performed to evaluate the interaction of microdots under switching chirality.
