Abstract
In the present work, we report a comprehensive investigation of dielectric and magnetic phase transition in single phase Dy(Fe0.5Cr0.5)O3 (DFC) bulk ceramics. The Rietveld refinement suggests that DFC exhibit orthorhombic crystal system with Pnma space group. The observed magnetic and structural properties of Dy(Fe0.5Cr0.5)O3 are distinct from both the parent compound DyFeO3 and DyCrO3. Temperature dependent dc-magnetic studies exhibit a complex sequence of three magnetic transitions (TN1Â =Â 261Â K, TN2 â¼ 115Â K & TN3 â¼ 14Â K) below 300Â K. The diffuse dielectric peaks were observed in high temperature dielectric studies near at 578Â K, indicates diffuse relaxor like dielectric transition. The complex impedance spectroscopic analysis suggests that Non-Debye type dielectric relaxation process is detected.
