Positive and negative exchange bias effects from magnetization reversal in Ho3+

The polycrystalline ceramics of Y1−xHoxFe0.5Cr0.5O3 (x = 0, 0.05 and 0.1) are synthesized by a sol-gel method. The magnetization reversal and exchange bias effect are investigated in single phase bulk Y1−xHoxFe0.5Cr0.5O3. Magnetic Ho3+ ion as a dopant is introduced into the system to confirm the inf
