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 (H0). 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 (∼250K) and by examining the temperature-dependent magnetization near the ferroelectric transition point (∼345K) between the two-dimensional charge-density-wave (CDW) state and the three-dimensional CDW state.Keywords
