摘要：

We report here the structural, magnetic and exchange bias in a well characterized single phase sample of Co(Cr0.9Co0.1)(2)O-4. A pronounced signature of thermal hysteresis in temperature dependent magnetic susceptibility curves is obtained across the lock-in transition T-L similar or equal to 10 K. Concomitantly, exchange bias is observed only below the lock-in transition (T-L similar or equal to 10 K). This indicates a possible coupling of exchange bias to the lock-in transition in this system. (C) 2014 Elsevier B.V. All rights reserved.
