Magnetars and fossil-field model of origin of magnetic field
  The evolution and genesis of Anomalous X-ray Pulsars and Soft Gamma ray Repeaters are investigated. The new arguments in favor of magnetar model are found. It is shown, that these objects are formed from more massive stars and responsible for their high magnetic fields is fossil-field model.
