Coupled optical and magnetic excitations can give rise to remarkably strong magneto-optic responses. This is particularly evident in van der Waals magnets, such as the antiferromagnet CrSBr, where excitons and magnons emerge from the same electronic orbitals. While previous work has primarily focused on uncovering the magneto-electric origin of the resulting exciton-magnon interactions, the influence of photonic effects has received comparatively little attention. Here, we use numerical simulations to disentangle exciton-magnon coupling from the exciton-mediated magnon-photon interactions observed in optical experiments. Our simulations show the strong dependence of these interactions on photonic interference and dispersion effects near excitonic resonances. Such effects shape the optical response to coherent magnons and make it intrinsically non-linear in the magnon-induced exciton energy shift. Thermal magnons, which have a particularly pronounced impact on excitons, are found to even produce qualitatively different trends in optical signatures. Depending on weak or strong coupling of excitons and photons, the same exciton-magnon interaction can lead to a red-shift of optical modes, a nearly vanishing response, or their blue-shift. Finally, we demonstrate first steps towards optimizing the multi-parameter problem of efficient magnon-photon transduction using a machine-learning approach.

Electric-field-induced strain-mediated magnetoelectric effect in CoFeB-MgO magnetic tunnel junctions
磁偶极子和电偶极子之间的磁电耦合是现代物理学发展最节能的磁数据存储的基石之一。传统上，磁电耦合是在单相多铁性或磁电复合纳米结构组成的铁磁和铁电/压电材料。本文利用动态磁电和压电响应力显微测量技术，研究了非压电材料的CoFeB/MgO磁性隧道结中的电场诱导应变介导磁电效应。研究表明，外加电场在介电MgO的几个原子层中引起应变，应变被转移到磁致伸缩CoFeB层，导致在-0.5 V下的幅度高达80.8 V cm-1 Oe-1的磁电效应。在磁性隧道结中利用电场介导的磁电效应是朝向探索磁电控制的自旋电子器件的重要一步，低功率和高密度磁数据存储应用。
