  Functional intermetallic materials such as Heusler compounds exhibit diff
 erent electronic ground states such as spin-density-wave ordering\, thermo
 electricity\, topological insulating properties\, first-order phase transi
 tions\, metamagnetic transitions\, high magnetic anisotropy\, high magneti
 c moments and Curie temperature\, as well as high spin polarization. This 
 diversity renders intermetallics attractive materials to explore fundament
 al aspects of matter but also raises interest for the technological exploi
 tation of their functionalities\, e.g.\, in spintronics devices.<br />The 
 key tool in the rational design of this class of materials is the knowledg
 e and control of the properties and whether they are dominated by intrinsi
 c factors (e.g. electronic structure) or by extrinsic factors (structural 
 degree of order\, segregation\, and phase dynamics). We address these issu
 es by combining crystal growth techniques with nuclear magnetic resonance 
 (NMR). Here\, we will illustrate this approach by discussing selected exam
 ples of the disentanglement of intrinsic and extrinsic properties in highl
 y functional Heusler materials and the resulting iterative optimization of
  their functional properties.
