Multiferroic materials have attracted much interest due to the unusual coexistence of
ferroelectric and (anti-) ferromagnetic ground states in a single compound. They offer an …

SmFeO 3 has attracted considerable attention very recently due to its reported multiferroic
properties above room temperature. We have performed powder and single crystal neutron …

After decades of study, BiFeO3 is still the most promising single‐phase multiferroic material
due to its large polarization and high operating temperature, drawing much attention. As a …

We have determined the full magnetic dispersion relations of multiferroic BiFeO 3. In
particular, two excitation gaps originating from magnetic anisotropies have been clearly …

Using the inelastic neutron scattering technique, we measured the spin wave dispersion
over the entire Brillouin zone of room temperature multiferroic BiFeO 3 single crystals with …

Resonant ultrasound spectroscopy (RUS) provides a window on the pervasive influence of
strain coupling at phase transitions in perovskites through determination of elastic and …

We have studied the magnetic field dependence of far-infrared active magnetic modes in a
single ferroelectric domain BiFeO 3 crystal at low temperature. The modes soften close to …

How magnetoelectric coupling actually occurs on a microscopic level in multiferroic BiFeO 3
is not well known. By using high-resolution single crystal neutron diffraction techniques, we …

Low-energy magnon excitations in multiferroic BiFeO 3 were measured in detail as a
function of temperature around several Brillouin zone centers by inelastic neutron scattering …

Multiferroics are materials that evince both ferroelectric and magnetic order parameters.
These order parameters when coupled can lead to both exciting new physics as well as new …
