Silicon with Magnetic Nanoclusters of Manganese Atoms as a New Ferromagnetic Material

详细

Photosensitivity of the negative magnetoresistance (NMR) of silicon containing magnetic nanoclusters of manganese atoms is revealed under background and IR (up to λ = 3 μm) irradiation at room temperature. It is shown that irradiation leads to a significant decrease in the NMR (NMR suppression) and sign inversion of the NMR at higher radiation intensities. Regularities of variations in the NMR and conditions for sign inversion are determined.
