We cover Black Magic Woman in our set. For my second solo I jam my interpretation of Santa's style. He likes to use the Aeolian mode quite a lot.
The harmonic minor scale is used a far amount in hard rock and heavy metal. The greatest exponents of it were technicians like Ritchie Blackmore and Michael Schenker, and it has been used more recently by the likes of Slash (main solo in Sweet Child of Mine) and Yngwie Malmsteen.
I've played Black Magic woman too. In fact, it was written by an old friend. That's mostly D natural minor scale, for me.
A better example of his use of harmonic minor would be 'Smooth', IMO.
