The effective spectrum of electron states in graphene in quantizing magnetic and high -frequency electric fields is calculated. The presence of the high-frequency held is shown to lead to the Landau levels splitting in graphene. The magnitude of this splitting is calculated. The influence of the high-frequency electric held on the magnetic oscillations of graphene conductivity is investigated. The possibility of controlling of conductivity oscillations by change of electric held amplitude is shown. (C) 2014 Elsevier B.V. All rights reserved.
