Abstract
We report on transport and magnetization measurements of the critical current density Jc in ErNi2B2C single crystals that show strongly enhanced vortex pinning at the Néel temperature TN and low applied fields. The height of the observed Jc peak decreases with increasing magnetic field in clear contrast with that of the peak effect found at the upper critical field. Angular transport measurements of Jc revealed the correlated nature of this pinning enhancement, which we attribute to the formation of antiphase boundaries at TN.
