  text: Studying and understanding many‐body interactions, particularly electron‐boson
    interactions, is essential for a deeper elucidation of fundamental physical phenomena
    and the development of novel material functionalities. Here, this aspect is explored
    in the weak itinerant ferromagnet LaCo2P2 by means of momentum‐resolved photoelectron
    spectroscopy (ARPES) and first‐principles calculations. The detailed ARPES patterns
    enable to unveil bulk and surface bands, spin splittings due to Rashba and exchange
    interactions, as well as the evolution of bands with temperature, which altogether
    creates a solid foundation for theoretical studies. The latter has allowed to
    establish the impact of electron‐boson interactions on the electronic structure,
    that are reflected in its strong renormalization driven by electron‐magnon interaction
    and the emergence of distinctive kinks of surface and bulk electron bands due
    to significant electron‐phonon coupling. Our results highlight the distinct impact
    of electron‐boson interactions on the electronic structure, particularly on the
    itinerant d states. Similar electronic states are observed in the isostructural
    iron pnictides, where electron‐boson interactions play a crucial role in the emergence
    of superconductivity. It is believed that further studies of material systems
    involving both magnetically active d‐ and f‐sublattices will reveal more advanced
    phenomena in the bulk and at distinct surfaces, driven by a combination of factors
    including Rashba and Kondo effects, exchange magnetism, and electron‐boson interactions.
