In the link to the referenced Nature article, they state this was done with zinc-blende-structured MnAs quantum nanomagnets. (Manganese Arsenide?)

Here is a PDF about making and characterizing MnAs nanostructures:

Direct large scale conversion of magnetic energy to electricity with no moving parts and no chemical reactions would definitely qualify as “Hugh and Series”...
