Abstract	The existence of radio pulsars having inferred magnetic fields in the magnetar regime suggests that possible transition objects could be found in the radio pulsar population. The discovery of such an object would contribute greatly to our understanding of neutron star physics. Here we report on unusual X-ray emission detected from the radio pulsar PSR J1119–6127 using XMM–Newton. The pulsar has a characteristic age of 1,700 yrs and inferred surface dipole magnetic field strength of 4.1×1013 G. In the 0.5–2.0 keV range, the emission shows a single, narrow pulse with an unusually high pulsed fraction of ∼70%. No pulsations are detected in the 2.0–10.0 keV range, where we derive an upper limit at the 99% level for the pulsed fraction of 28%. The pulsed emission is well described by a thermal blackbody model with a high temperature of ∼2.4×106 K. While no unambiguous signature of magnetar-like emission has been found in high-magnetic-field radio pulsars, the X-ray characteristics of PSR J1119–6127 require alternate models from those of conventional thermal emission from neutron stars. In addition, PSR J1119–6127 is now the radio pulsar with the smallest characteristic age from which thermal X-ray emission has been detected.
