The perovskite chromite La1-xPrxCrO3 shows an unusual positive exchange bias (PEB) and a negative exchange bias (NEB) associated with magnetization reversal, arising from an antiparallel Pr3+-Cr3+ coupling. Below similar to 200 K, changing the cooling magnetic field switches the type of EB. A PEB appears in low cooling fields (<3-15 kOe), comparable with the internal magnetic field at the Pr site. The appearance of PEB or NEB depends on the orientation of the Pr3+ moment with respect to the canted Cr3+ component. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3644473]
