Abstract

A multiglass state in which two distinct glassy phases coexist has been identified in multiferroic YbFe 2O 4. A collective magnetic freezing, as evidenced by AC susceptibility, magnetization, and coercivity measurements, develops at a freezing temperature T F ∼ 80 K. Meanwhile, the low-temperature dielectric and pyroelectric measurements suggest that an electric polar-glass state develops at the same freezing temperature. The simultaneous freezing of spin and polar clusters implies a strong magnetoelectric coupling and leads to a magnetoelectric multiglass state. © 2012 American Institute of Physics.
