Polar or non-centrosymmetric ferri(-o)magnets offer a plethora of potential technological devices; the inherent magnetoelectric effect can underpin both pyroelectric or multiferroic functionality. This will enable new functionality in electronic devices providing new benefits to consumers. For academic study, modulated magnetic structures, a prerequisite for skyrmion formation, can be stabilized via the Dzyaloshinskii-Moriya interaction (DMI) induced by the polar nature of the structure. These structures have been predicted to host a new type of magnons emerging from the multiferroic nature, the so called the electromagnon. These experiments are designed to probe the crystal and magnetic structure of a new candidate for these phenomena; BaCaFe4O7.
