- Abstract
- Magnetoelectric (ME) coupling characteristics of LuFe2O4 were examined by monitoring the electrical voltage induced by an oscillating magnetic field under a static bias field (H-0). Interestingly, the room-temperature dynamic ME output exhibited a constant plateau behavior up to a certain static-field strength but showed a sudden drop above this critical value. In addition, two evidences of the intrinsic ME coupling were obtained by monitoring the pyroelectric response near the ferrimagnetic ordering temperature (similar to 250 K) and by examining the temperature-dependent magnetization near the ferroelectric transition point (similar to 345 K) between the two-dimensional charge-density-wave (CDW) state and the three-dimensional CDW state.
