Here we demonstrate an encouraging example of this strategy with a newly synthesized Fe-based Heterolayered Silicide, Y4FeSi8, in single-crystal form. The crystal structure of Y4FeSi8 consists of two distinct functional layers (of edge-sharing Fe-Si square pyramidal) separated by non-magnetic spacer layers ( of double vertical honeycomb Y-Si layers). The synthesis method of this new heterolayered Fe-based silicide will be discussed along with physical properties confirming the superconductivity transition.
