Crystal Field-Phonon Coupling in ErFeO Single Crystal Via Inelastic Neutron Scattering
Guochu Deng, Xiaoxuan Ma, Wanting Yang +4
Crystal-field (CF) excitations and their coupling to lattice vibrations were investigated in ErFeO using inelastic neutron scattering. Pronounced modifications of the excitatio…

Large Energy Shifts of Crystal-field Excitations in Erbium Orthoferrite Driven by Internal Magnetic Fields
Guochu Deng, Xiaoxuan Ma, Zhenjie Feng +5
Due to the complex interactions between rare-earth elements and transition metals, as well as between themselves, rare-earth transition-metal oxides are likely to exhibit highly in…
