  Several aspects of the magnetospheric physics of magnetars are summarized,
including: GeV and hard X-ray emissions of magnetars, timing behaviors during
magnetar outburst (soft X-ray observations), optical/IR observations of
magnetars, radio emission of magnetars, and accreting magnetars. A unified
picture for pulsars and magnetars are adopted, especially wind braking of
magnetars, magnetar+ fallback disk systems, twisted dipole magnetic field, and
accreting low magnetic field magnetars etc. It is pointed out that magnetars
are related to a broad range of astrophysical phenomena.
