Shandite Co3Sn2S2 - story and news — •Richard Weihrich — University of Augsburg, Regensburg, Germany

Shandite type compounds turned into focus with recent discoveries on Sn2Co3S2 = Co3Sn2S2 i.e. giant anomalous hall effects and magnetic Weyl semi metal characteristics. The compound was first synthesized and characterized in Regensburg in 1979 by Zabel and Range. After 2 decades the half metal ferromagnetism of highly anisotropic Sn2Co3S2 was discovered by DFT calculations in Regensburg, too. The story of the compound, discoveries and new results are reported and discussed.
