Abstract. Pulsars are fast-rotating neutron stars with strong magnetic fields. Magnetars are pulsars with extraordinarily strong magnetic fields and remarkable for the bursting activities and high X-ray luminosities. However, recent discoveries blurred the boundary between magnetars and rotation-powered pulsars (RPPs). In this talk, I will introduce the recent works on the high-magnetic-field RPPs, especially the youngest ones of J1846-0258, J1119-6127, and B1509-58. Young and high-magnetic-field RPPs have surface temperatures between the magnetars and canonical RPPs, indicating that high-magnetic-field RPPs are potential bursters and may contain toroidal magnetic fields according to the magneto-thermal evolution model. This model implies that the toroidal field could play an important role in bursting rate and break the surface temperature symmetry. Our recent work suggested that the distribution of magnetar's pulse profile cannot be explained by a symmetric surface temperature distribution with an arbitrary viewing angle. This result agreed with the implication of the magneto-thermal evolution.
