Heusler alloys have attracted a considerable attention in recent years since these compounds are predicted to be halfmetallic ferromagnets. High magnetic moments and high values of the Curie temperature give them a significant potential for spintronics applications. To control the macroscopic physical properties of these materials it is crucial to have a precise knowledge of the structural and magnetic ordering also on a local scale. For instance, the halfmetallicity in these materials strongly depends on the local atomic order. To obtain such knowledge one has to call for local probe techniques. In this work we present recent nuclear magnetic resonance and electron spin resonance study of various Co-, Mn- and Fe-based Heusler compounds where we address the local structural and magnetic properties.
