  • Description: <jats:sec><jats:label /><jats:p>Magnetic resonance techniques at nuclei and electrons are applied to characterize the electronic structure and collective magnetic excitations throughout the magnetic phase diagrams of the lacunar spinels GaV<jats:sub>4</jats:sub>S<jats:sub>8</jats:sub> and GaV<jats:sub>4</jats:sub>Se<jats:sub>8</jats:sub> showing cycloidal, Néel‐type skyrmion lattice and ferromagnetically polarized phases. <jats:sup>71</jats:sup>Ga nuclear magnetic resonance (NMR) provides a local probe of the rhombohedral distortion and the resulting uniaxial magnetic anisotropy via the detection of electric field gradients (EFGs) and hyperfine coupling at the gallium sites of these lacunar spinels. Broadband electron spin resonance (ESR) allows identifying clockwise, counterclockwise, and breathing modes of the skyrmion‐lattice phase supported by theoretical simulations.</jats:p></jats:sec>
