We report experimental evidence of this longitudinal spin-resonator interaction where the resonator is affected by the spins polarization for detunings between the spin and the resonator larger than 1 GHz, where the contribution of the dispersive interaction is vanishing. In the specific implementation, numerical simulations show that the main contributions come from near-surface spins. This novel coupling can lead to new characterization tools and methods of quantum defects, complex quantum materials and many other paramagnetic systems.
