Role of the ferromagnetic component in the ferroelectricity of YMnO3
Kiran Singh, Natalia Bellido, Charles Simon +4
We performed magnetic and ferroelectric measurements, first principle calculations and Landau theory analysis on hexagonal YMnO3. The polarization and the AFM order parameter were…

Multiferroicity and magnetoelectric coupling in α-CaCr2O4
Kiran Singh, Charles Simon, Pierre Toledano
Ferroelectricity in the incommensurate helical magnetic phase (below TN, 43K) of alpha CaCr2O4 has been confirmed by pyroelectric measurements. Magnetoelectric and magnetodielectri…
