Spin excitation spectroscopy has proven to be an essential tool for the investigation of magnetic phenomena at the atomic scale [1] forming the basis for RF-STM investigation of both electron spin resonance and spin dynamics [2]. However, certain spin dynamic phenomena can also be transduced directly via standard dIdV(V) measurements [3]. Here, the contribution of spin dynamic effects to static spectroscopy measurements is presented using a combined theoretical and experimental approach. Understanding these phenomena allows the behavior of spin systems with long-lived excitations to be anticipated, offering a fast and reliable way to access spin dynamics with standard STM techniques.
