| Abstract | |
Positive and negative exchange bias effects are observed in Nd1-xPrxCrO3 (0.00 <= x <= 1.00) polycrystalline samples. The shift of hysteresis loops, either opposing or following the direction of the field cooling, de -pends on the concentration of praseodymium. The temperature dependence of magnetization reveals a magnetic transition at T approximate to 220 K likely ascribed to the N e el temperature of Cr3+ magnetic moments. The non-Kramer Pr3+ ion seems to play an important role in the magnetic properties of this compound. In the range 0.00 <= x <= 0.60, all samples presented a decrease in the magnetization below TN and a clear com-pensation point. Pr-rich samples (x >= 0.70) show a paramagnetic-like behavior down to low temperatures. The most impressive result is the relation between reversal magnetization and the signal of exchange bias effect which seems be tuned by the Pr-doping.(c) 2022 Elsevier B.V. All rights reserved.
