AbstractMagnetars are proposed to be peculiar neutron stars powered by their super-strong magnetic field. Observationally, anomalous X-ray pulsars and soft gamma-ray repeaters are believed to be magnetar candidates. While more and more multiwave observations of magnetars are available, we see unfortunately an accumulation of failed predictions of the traditional magnetar model. These challenges urge a reconsidering of the magnetar phenomenon. Wind braking of magnetars is one of the alternative modelings. The release of magnetic energy may generate a particle outflow (i.e., particle wind) which results in both an anomalous X-ray luminosity (L-X) and a significantly high spindown rate (P). In this wind braking scenario, only a strong multipole field is necessary for a magnetar (a strong dipole field is no longer needed). Wind braking of magnetars may help us to understand their multiwave radiation properties, including (1) non-detection of magnetars in the Fermi-LAT observations, (2) timing behaviors of low magnetic field magnetars, (3) nature of anti-glitches, (4) criterion for magnetar radio emission, etc. In the wind braking model of magnetars, timing events of magnetars should always be accompanied by radiative events.
