Abstract
It is analytically indicated that self-generated magnetic fields are modulationally unstable with respect to the uniform state of a plasma; such an instability would cause the formation of the field localization. It is able to expect that this localized magnetic flux is responsible for small-scale inhomogeneous magnetic fields, which are required for explanation of the fine structure of auroral kilometric radiaton (AKR).
