The current instabilities in silicon with nanoclusters of manganese atoms in accordance with the excitation conditions and the control possibilities for the oscillation parameters discovered by us differ substantially from the current instability found in many other semiconductor materials [1-3]. This is due to the onset of generation of current instability only under illumination by certain wavelengths under the condition of a sufficiently low IR light intensity, as well as a pronounced dependence of the current frequency frequency on the energy of the incident photons. It should be noted that such instabilities of current are observed only in silicon samples …

Magnetohydrodynamic turbulence driven by magnetorotational instability (MRI) has been widely accepted as an efficient mechanism for transporting angular momentum radially outward in the discs. Previously, we have shown the triggering effect of the magnetization currents and the gradients produced by these currents on MRI for Keplerian discs. In this work, we examine the properties of the diamagnetic current modified MRI for the discs where the epicyclic frequencies deviate from Keplerian behaviour. We show that the diamagnetic effect modifies the instability both for an increasing and for a decreasing angular momentum with radius. The novel unstable region produced by magnetization effects …
