Mechanical properties of multiferroic Bi2Mn4O10: Full set of elastic constants determined by inelastic neutron scattering

Abstract: The full matrix of elastic constants of multiferroic Bi2Mn4O10 has been determined at ambient conditions using phonon spectroscopy. The dispersion of acoustic phonons in a single crystal was measured at the three axes neutron spectrometer PUMA@FRM II for different propagation directions. The magnitudes of the independent nine elastic constants show that the mechanical behavior is strongly anisotropic with a soft direction which almost coincides with the magnetization vector in the low‐temperature multiferroic … Show more

“…Moreover, it has been shown by Curti et al that the electron lone‐pair of bismuth is located in the direction toward the basal planes of the Mn 3+ O 5 ‐pyramids, which could also support the hopping of electrons along b . The anisotropy of the elastic constants (sound velocities) is another consequence of this enhanced interaction since the a ‐direction was found to be significantly softer than b or c …”
