Unraveling Spin Excitations, Competing Exchange Interactions, and Magnon Phonon Coupling in Magnetically Frustrated Multiferroic CaFe3O(PO4)3
Abstract: CaFe3O(PO4)3 is a magnetically frustrated multiferroic that exhibits competing exchange interactions, multiple magnetic transitions, and field-induced ferroelectricity. We propose inelastic neutron scattering measurements to investigate its spin dynamics and microscopic exchange mechanisms. Bulk measurements show two magnetic transitions near 19.5 K and 9 K, strong antiferromagnetic interactions, and significant frustration, indicating complex magnetic ordering driven by competing interactions among inequivalent Fe sites. The proposed study aims to determine the nature of magnetic excitations, including spin waves, anisotropy gaps, or possible diffuse continua associated with frustration. We will examine the evolution of excitations across the magnetic transitions to understand the origin of multiple ordered phases. In addition, the role of the three distinct Fe sites in governing exchange interactions will be quantified through modeling of the spectra.
