A new model of the electron-hole pair magnetic polaron lattice formation in magnetic semimetals is proposed and the stability condition is studied on a simple model. It is shown that in Ce-monopnictides the conduction electrons form either neutral electron-hole pair magnetic polaron or extended band states loosely coupling with hole induces magnetic polaron. Various anomalous properties in CeSb under high pressure are explained well by this model.
