The artwork depicts the magnetic and electronic states of the newly discovered magnetic topological semimetal (Sr1-yMn1-zSb2); its unusual and robust electronic behavior enables the flow of electrical current with little resistance. The violet spheres are strontium (Sr), blue is antimony (Sb), and purple is manganese (Mn). Arrows represent the alignment of magnetic moments. The two gold cones touching at a point (called Dirac point) represent the energy and momentum states of conducting electrons.
