Multiferroic order and re-entrant spin-glass-like state in DyCrO4
Abstract
We report intrinsic memory effect in magnetization for zircon-type DyCrO4, pointing the cooperative glassy response below ∼ 7 K. Intriguingly, the memory effect is observed well below the ferromagnetic and antiferromagnetic ordering temperatures, indicate re-entrant spin-glass state in DyCrO4. Above the magnetic order ferroelectricity emerges with a ferroelectric TC at 97 K, which is associated with a signature of magnetoelectric coupling. Thus DyCrO4 attracts the community for multiple interesting properties with a high temperature ferroelectricity and low temperature re-entrant spin-glass-like behavior.
