Crystal Field-Phonon Coupling in ErFeO$_3$ Single Crystal Via Inelastic Neutron Scattering

Crystal-field (CF) excitations and their coupling to lattice vibrations were investigated in ErFeO$_3$ using inelastic neutron scattering. Pronounced modifications of the excitation spectra, including energy shifts, intensity redistribution, and linewidth changes, were observed as a consequence of CF-phonon coupling. S...

Ferroelectric Control of Layer-Resolved Spin and Orbital Transport in a Topological Heterobilayer.

Ferroelectric switching in van der Waals heterostructures provides a powerful route to reconfiguring quantum states and their associated transport responses. Here, we propose a ferroelectric topological heterobilayer in which the stepwise reversal of polarization in the two monolayers enables selective control of spin...
