  The Landau quantization for the electron gas on a surface of sphere is
considered. We show that in the regime of strong fields the lowest energy
states are those with magnetic quantum numbers m of order of Phi/Phi_0, the
number of magnetic flux quanta piercing the sphere. For the electron gas of low
density (semiconducting situation), it leads to the formation of the electronic
stripe on the equator of the sphere in high fields.
