With the recent discovery of radio pulsations from an anomalous X-ray pulsar, it is clear that magnetars and ordinary rotation-powered pulsars can no longer be accepted as two distinct classes of neutron stars. To better understand the exotic physics of magnetars and the possible evolutionary links between rotation-powered pulsars and magnetars, we must examine their common characteristics. The radio pulsar PSR J1718-3718 has a very high inferred magnetic field of B=7.4x10^13 G, even higher than that of one AXP, and is the first high-B radio pulsar to been seen in X-rays. Apparently, this pulsar already has much in common with AXPs, and we further explore that link by looking at near-infrared wavelengths. Optical/near-IR emission from AXPs, although not explicitly accounted for by the magnetar model, has been attributed to their high magnetic field strengths, suggesting it could be detectable in high-B rotation-powered pulsars as well. Here, we present preliminary results from near-IR observations of PSR J1718-3718 with the NIRI instrument on the Gemini-North Telescope.
